"""Exponential and Quaternion code for Lab 6.
Course: EE 106, Fall 2015
Author: Victor Shia, 9/24/15
This Python file is a code skeleton Lab 6 which calculates the rigid body transform
given a rotation / translation and computes the twist from rigid body transform.
When you think you have the methods implemented correctly, you can test your
code by running "python exp_quat_func.py at the command line.
This code requires the NumPy and SciPy libraries and kin_func_skeleton which you
should have written in lab 3. If you don't already have
these installed on your personal computer, you can use the lab machines or
the Ubuntu+ROS VM on the course page to complete this portion of the homework.

/// A trait for objects which can be converted or resolved to one or more

///
/// This trait is used for generic address resolution when constructing network
/// objects. By default it is implemented for the following types:
///
/// * `SocketAddr`, `SocketAddrV4`, `SocketAddrV6` - `to_socket_addrs` is
/// identity function.
///
/// * `(IpvNAddr, u16)` - `to_socket_addrs` constructs `SocketAddr` trivially.
///
/// * `(&str, u16)` - the string should be either a string representation of an
/// IP address expected by `FromStr` implementation for `IpvNAddr` or a host
/// name.
///
/// * `&str` - the string should be either a string representation of a
/// `SocketAddr` as expected by its `FromStr` implementation or a string like
/// `<host_name>:<port>` pair where `<port>` is a `u16` value.
///
/// This trait allows constructing network objects like `TcpStream` or
/// `UdpSocket` easily with values of various types for the bind/connection
/// address. It is needed because sometimes one type is more appropriate than
/// the other: for simple uses a string like `"localhost:12345"` is much nicer
/// than manual construction of the corresponding `SocketAddr`, but sometimes
/// `SocketAddr` value is *the* main source of the address, and converting it to
/// some other type (e.g. a string) just for it to be converted back to
/// `SocketAddr` in constructor methods is pointless.
///
/// Some examples:
///
/// ```no_run
/// use std::net::{SocketAddrV4, TcpStream, UdpSocket, TcpListener, Ipv4Addr};
///
/// fn main() {
/// let ip = Ipv4Addr::new(127, 0, 0, 1);
/// let port = 12345;
///
/// // The following lines are equivalent modulo possible "localhost" name
/// // resolution differences
/// let tcp_s = TcpStream::connect(SocketAddrV4::new(ip, port));
/// let tcp_s = TcpStream::connect((ip, port));
/// let tcp_s = TcpStream::connect(("127.0.0.1", port));
/// let tcp_s = TcpStream::connect(("localhost", port));
/// let tcp_s = TcpStream::connect("127.0.0.1:12345");
/// let tcp_s = TcpStream::connect("localhost:12345");
///
/// // TcpListener::bind(), UdpSocket::bind() and UdpSocket::send_to()
/// // behave similarly
/// let tcp_l = TcpListener::bind("localhost:12345");
///
/// let mut udp_s = UdpSocket::bind(("127.0.0.1", port)).unwrap();

@private
In order to store defaults for a class, a prototype may need to create
a default meta object, which will be inherited by any objects instantiated
from the class's constructor.
However, the properties of that meta object are only shallow-cloned,
so if a property is a hash (like the event system's `listeners` hash),
it will by default be shared across all instances of that class.
This method allows extensions to deeply clone a series of nested hashes or
other complex objects. For instance, the event system might pass
`['listeners', 'foo:change', 'ember157']` to `prepareMetaPath`, which will
walk down the keys provided.
For each key, if the key does not exist, it is created. If it already
exists and it was inherited from its constructor, the constructor's
key is cloned.
You can also pass false for `writable`, which will simply return
undefined if `prepareMetaPath` discovers any part of the path that
shared or undefined.

The purpose of the Ember Instrumentation module is
to provide efficient, general-purpose instrumentation
for Ember.
Subscribe to a listener by using `Ember.subscribe`:
```javascript
Ember.subscribe("render", {
before: function(name, timestamp, payload) {
},
after: function(name, timestamp, payload) {
}
});
```
If you return a value from the `before` callback, that same
value will be passed as a fourth parameter to the `after`
callback.
Instrument a block of code by using `Ember.instrument`:
```javascript
Ember.instrument("render.handlebars", payload, function() {
// rendering logic
}, binding);
```
Event names passed to `Ember.instrument` are namespaced
by periods, from more general to more specific. Subscribers
can listen for events by whatever level of granularity they
are interested in.
In the above example, the event is `render.handlebars`,
and the subscriber listened for all events beginning with
`render`. It would receive callbacks for events named
`render`, `render.handlebars`, `render.container`, or
even `render.handlebars.layout`.

JavaScript (before ES6) does not have a Map implementation. Objects,
which are often used as dictionaries, may only have Strings as keys.
Because Ember has a way to get a unique identifier for every object
via `Ember.guidFor`, we can implement a performant Map with arbitrary
keys. Because it is commonly used in low-level bookkeeping, Map is
implemented as a pure JavaScript object for performance.
This implementation follows the current iteration of the ES6 proposal for
maps (http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets),
with two exceptions. First, because we need our implementation to be pleasant
on older browsers, we do not use the `delete` name (using `remove` instead).
Second, as we do not have the luxury of in-VM iteration, we implement a
forEach method for iteration.
Map is mocked out to look like an Ember object, so you can do
`Ember.Map.create()` for symmetry with other Ember classes.

NOTE: This is a low-level method used by other parts of the API. You almost
never want to call this method directly. Instead you should use
`Ember.mixin()` to define new properties.
Defines a property on an object. This method works much like the ES5
`Object.defineProperty()` method except that it can also accept computed
properties and other special descriptors.
Normally this method takes only three parameters. However if you pass an
instance of `Ember.Descriptor` as the third param then you can pass an
optional value as the fourth parameter. This is often more efficient than
creating new descriptor hashes for each property.
## Examples
```javascript
// ES5 compatible mode
Ember.defineProperty(contact, 'firstName', {
writable: true,
configurable: false,
enumerable: true,
value: 'Charles'
});
// define a simple property
Ember.defineProperty(contact, 'lastName', undefined, 'Jolley');
// define a computed property
Ember.defineProperty(contact, 'fullName', Ember.computed(function() {
return this.firstName+' '+this.lastName;
}).property('firstName', 'lastName'));
```
@method defineProperty
@for Ember
@param {Object} obj the object to define this property on. This may be a prototype.
@param {String} keyName the name of the property
@param {Ember.Descriptor} [desc] an instance of `Ember.Descriptor` (typically a
computed property) or an ES5 descriptor.
You must provide this or `data` but not both.
@param {anything} [data] something other than a descriptor, that will
become the explicit value of this property.

/**
An `Ember.Binding` connects the properties of two objects so that whenever
the value of one property changes, the other property will be changed also.
## Automatic Creation of Bindings with `/^*Binding/`-named Properties
You do not usually create Binding objects directly but instead describe
bindings in your class or object definition using automatic binding
detection.
Properties ending in a `Binding` suffix will be converted to `Ember.Binding`
instances. The value of this property should be a string representing a path
to another object or a custom binding instanced created using Binding helpers
(see "Customizing Your Bindings"):
```
valueBinding: "MyApp.someController.title"
```
This will create a binding from `MyApp.someController.title` to the `value`
property of your object instance automatically. Now the two values will be
kept in sync.
## One Way Bindings
One especially useful binding customization you can use is the `oneWay()`
helper. This helper tells Ember that you are only interested in
receiving changes on the object you are binding from. For example, if you
are binding to a preference and you want to be notified if the preference
has changed, but your object will not be changing the preference itself, you
could do:
```
bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
```
This way if the value of `MyApp.preferencesController.bigTitles` changes the
`bigTitles` property of your object will change also. However, if you
change the value of your `bigTitles` property, it will not update the
`preferencesController`.
One way bindings are almost twice as fast to setup and twice as fast to
execute because the binding only has to worry about changes to one side.
You should consider using one way bindings anytime you have an object that
may be created frequently and you do not intend to change a property; only
to monitor it for changes. (such as in the example above).
## Adding Bindings Manually
All of the examples above show you how to configure a custom binding, but the
result of these customizations will be a binding template, not a fully active
Binding instance. The binding will actually become active only when you
instantiate the object the binding belongs to. It is useful however, to
understand what actually happens when the binding is activated.
For a binding to function it must have at least a `from` property and a `to`
property. The `from` property path points to the object/key that you want to
bind from while the `to` path points to the object/key you want to bind to.
When you define a custom binding, you are usually describing the property
you want to bind from (such as `MyApp.someController.value` in the examples
above). When your object is created, it will automatically assign the value
you want to bind `to` based on the name of your binding key. In the
examples above, during init, Ember objects will effectively call
something like this on your binding:
```javascript
binding = Ember.Binding.from(this.valueBinding).to("value");
```
This creates a new binding instance based on the template you provide, and
sets the to path to the `value` property of the new object. Now that the
binding is fully configured with a `from` and a `to`, it simply needs to be
connected to become active. This is done through the `connect()` method:
```javascript
binding.connect(this);
```
Note that when you connect a binding you pass the object you want it to be
connected to. This object will be used as the root for both the from and
to side of the binding when inspecting relative paths. This allows the
binding to be automatically inherited by subclassed objects as well.
Now that the binding is connected, it will observe both the from and to side
and relay changes.
If you ever needed to do so (you almost never will, but it is useful to
understand this anyway), you could manually create an active binding by
using the `Ember.bind()` helper method. (This is the same method used by
to setup your bindings on objects):
```javascript
Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value");
```
Both of these code fragments have the same effect as doing the most friendly
form of binding creation like so:
```javascript
MyApp.anotherObject = Ember.Object.create({
valueBinding: "MyApp.someController.value",
// OTHER CODE FOR THIS OBJECT...
});
```
Ember's built in binding creation method makes it easy to automatically
create bindings for you. You should always use the highest-level APIs
available, even if you understand how it works underneath.

|---------------|------------------------------------------------------|
| 'string' | String primitive |
| 'number' | Number primitive |
| 'boolean' | Boolean primitive |
| 'null' | Null value |
| 'undefined' | Undefined value |
| 'function' | A function |
| 'array' | An instance of Array |
| 'class' | A Ember class (created using Ember.Object.extend()) |
| 'instance' | A Ember object instance |

The `property` extension of Javascript's Function prototype is available

Computed properties allow you to treat a function like a property:
```javascript
MyApp.president = Ember.Object.create({
firstName: "Barack",
lastName: "Obama",
fullName: function() {
return this.get('firstName') + ' ' + this.get('lastName');
// Call this flag to mark the function as a property
}.property()
});
MyApp.president.get('fullName'); // "Barack Obama"
```
Treating a function like a property is useful because they can work with
bindings, just like any other property.
Many computed properties have dependencies on other properties. For
example, in the above example, the `fullName` property depends on
`firstName` and `lastName` to determine its value. You can tell Ember
about these dependencies like this:
```javascript
MyApp.president = Ember.Object.create({
firstName: "Barack",
lastName: "Obama",
fullName: function() {
return this.get('firstName') + ' ' + this.get('lastName');
// Tell Ember.js that this computed property depends on firstName
// and lastName
}.property('firstName', 'lastName')
});
```
Make sure you list these dependencies so Ember knows when to update
bindings that connect to a computed property. Changing a dependency
will not immediately trigger an update of the computed property, but
will instead clear the cache so that it is updated when the next `get`
is called on the property.

/**
This mixin defines the common interface implemented by enumerable objects
in Ember. Most of these methods follow the standard Array iteration
API defined up to JavaScript 1.8 (excluding language-specific features that
cannot be emulated in older versions of JavaScript).
This mixin is applied automatically to the Array class on page load, so you
can use any of these methods on simple arrays. If Array already implements
one of these methods, the mixin will not override them.
## Writing Your Own Enumerable
To make your own custom class enumerable, you need two items:
1. You must have a length property. This property should change whenever
the number of items in your enumerable object changes. If you using this
with an `Ember.Object` subclass, you should be sure to change the length
property using `set().`
2. If you must implement `nextObject().` See documentation.
Once you have these two methods implement, apply the `Ember.Enumerable` mixin
to your class and you will be able to enumerate the contents of your object
like any other collection.
## Using Ember Enumeration with Other Libraries
Many other libraries provide some kind of iterator or enumeration like
facility. This is often where the most common API conflicts occur.
Ember's API is designed to be as friendly as possible with other
libraries by implementing only methods that mostly correspond to the
JavaScript 1.8 API.

/**
Implement this method to make your class enumerable.
This method will be call repeatedly during enumeration. The index value
will always begin with 0 and increment monotonically. You don't have to
rely on the index value to determine what object to return, but you should
always check the value and start from the beginning when you see the
requested index is 0.
The `previousObject` is the object that was returned from the last call
to `nextObject` for the current iteration. This is a useful way to
manage iteration if you are tracing a linked list, for example.
Finally the context parameter will always contain a hash you can use as
a "scratchpad" to maintain any other state you need in order to iterate
properly. The context object is reused and is not reset between
iterations so make sure you setup the context with a fresh state whenever
the index parameter is 0.
Generally iterators will continue to call `nextObject` until the index
reaches the your current length-1. If you run out of data before this
time for some reason, you should simply return undefined.
The default implementation of this method simply looks up the index.
This works great on any Array-like objects.
@method nextObject
@param {Number} index the current index of the iteration

/**
This module implements Observer-friendly Array-like behavior. This mixin is
picked up by the Array class as well as other controllers, etc. that want to
appear to be arrays.
Unlike `Ember.Enumerable,` this mixin defines methods specifically for
collections that provide index-ordered access to their contents. When you
are designing code that needs to accept any kind of Array-like object, you
should use these methods instead of Array primitives because these will
properly notify observers of changes to the array.
Although these methods are efficient, they do add a layer of indirection to
your application so it is a good idea to use them only when you need the
flexibility of using both true JavaScript arrays and "virtual" arrays such
as controllers and collections.
You can use the methods defined in this module to access and modify array
contents in a KVO-friendly way. You can also be notified whenever the
membership if an array changes by changing the syntax of the property to
`.observes('*myProperty.[]')`.
To support `Ember.Array` in your own class, you must override two
primitives to use it: `replace()` and `objectAt()`.
Note that the Ember.Array mixin also incorporates the `Ember.Enumerable`
mixin. All `Ember.Array`-like objects are also enumerable.

/**
The `Ember.Freezable` mixin implements some basic methods for marking an
object as frozen. Once an object is frozen it should be read only. No changes
may be made the internal state of the object.
## Enforcement
To fully support freezing in your subclass, you must include this mixin and
override any method that might alter any property on the object to instead
raise an exception. You can check the state of an object by checking the
`isFrozen` property.
Although future versions of JavaScript may support language-level freezing
object objects, that is not the case today. Even if an object is freezable,
it is still technically possible to modify the object, even though it could
break other parts of your application that do not expect a frozen object to
change. It is, therefore, very important that you always respect the
`isFrozen` property on all freezable objects.
## Example Usage
The example below shows a simple object that implement the `Ember.Freezable`
protocol.
```javascript
Contact = Ember.Object.extend(Ember.Freezable, {
firstName: null,
lastName: null,
// swaps the names
swapNames: function() {
if (this.get('isFrozen')) throw Ember.FROZEN_ERROR;
var tmp = this.get('firstName');
this.set('firstName', this.get('lastName'));
this.set('lastName', tmp);
return this;
}
});
c = Context.create({ firstName: "John", lastName: "Doe" });
c.swapNames(); // returns c
c.freeze();
c.swapNames(); // EXCEPTION
```
## Copying
Usually the `Ember.Freezable` protocol is implemented in cooperation with the
`Ember.Copyable` protocol, which defines a `frozenCopy()` method that will
return a frozen object, if the object implements this method as well.
@class Freezable
@namespace Ember
@extends Ember.Mixin
@since Ember 0.9
*/
Ember.Freezable = Ember.Mixin.create(
/** @scope Ember.Freezable.prototype */ {

whether your object is frozen or not.
@property isFrozen
@type Boolean
*/

no longer allow any properties to be edited.
@method freeze
@return {Object} receiver
*/

if (get(this, 'isFrozen')) return this;
set(this, 'isFrozen', true);
return this;
}
});

/**
This mixin defines the API for modifying generic enumerables. These methods

unordered.
Note that an Enumerable can change even if it does not implement this mixin.
For example, a MappedEnumerable cannot be directly modified but if its
underlying enumerable changes, it will change also.
## Adding Objects
To add an object to an enumerable, use the `addObject()` method. This
method will only add the object to the enumerable if the object is not
already present and the object if of a type supported by the enumerable.
```javascript
set.addObject(contact);
```
## Removing Objects
To remove an object form an enumerable, use the `removeObject()` method. This
will only remove the object if it is already in the enumerable, otherwise
this method has no effect.
```javascript
set.removeObject(contact);
```

## Overview
This mixin provides properties and property observing functionality, core
features of the Ember object model.
Properties and observers allow one object to observe changes to a
property on another object. This is one of the fundamental ways that
models, controllers and views communicate with each other in an Ember
application.
Any object that has this mixin applied can be used in observer
operations. That includes `Ember.Object` and most objects you will
interact with as you write your Ember application.
Note that you will not generally apply this mixin to classes yourself,
but you will use the features provided by this module frequently, so it
is important to understand how to use it.
## Using `get()` and `set()`
Because of Ember's support for bindings and observers, you will always
access properties using the get method, and set properties using the
set method. This allows the observing objects to be notified and
computed properties to be handled properly.
More documentation about `get` and `set` are below.
## Observing Property Changes
You typically observe property changes simply by adding the `observes`
call to the end of your method declarations in classes that you write.
For example:
```javascript
Ember.Object.create({
valueObserver: function() {
// Executes whenever the "value" property changes
}.observes('value')
});
```
Although this is the most common way to add an observer, this capability
is actually built into the `Ember.Object` class on top of two methods
defined in this mixin: `addObserver` and `removeObserver`. You can use
these two methods to add and remove observers yourself if you need to
do so at runtime.
To add an observer for a property, call:
```javascript
object.addObserver('propertyKey', targetObject, targetAction)
```
This will call the `targetAction` method on the `targetObject` to be called
whenever the value of the `propertyKey` changes.
Note that if `propertyKey` is a computed property, the observer will be
called when any of the property dependencies are changed, even if the
resulting value of the computed property is unchanged. This is necessary
because computed properties are not computed until `get` is called.
@class Observable
@namespace Ember
@extends Ember.Mixin
*/
Ember.Observable = Ember.Mixin.create(/** @scope Ember.Observable.prototype */ {
/**
Retrieves the value of a property from the object.
This method is usually similar to using `object[keyName]` or `object.keyName`,
however it supports both computed properties and the unknownProperty
handler.
Because `get` unifies the syntax for accessing all these kinds
of properties, it can make many refactorings easier, such as replacing a
simple property with a computed property, or vice versa.
### Computed Properties
Computed properties are methods defined with the `property` modifier
declared at the end, such as:
```javascript
fullName: function() {
return this.getEach('firstName', 'lastName').compact().join(' ');
}.property('firstName', 'lastName')
```
When you call `get` on a computed property, the function will be
called and the return value will be returned instead of the function
itself.
### Unknown Properties
Likewise, if you try to call `get` on a property whose value is
`undefined`, the `unknownProperty()` method will be called on the object.
If this method returns any value other than `undefined`, it will be returned
instead. This allows you to implement "virtual" properties that are
not defined upfront.
@method get
@param {String} key The property to retrieve
@return {Object} The property value or undefined.
*/
get: function(keyName) {
return get(this, keyName);

with a list of strings or an array:
```javascript
record.getProperties('firstName', 'lastName', 'zipCode'); // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
```
is equivalent to:
```javascript
record.getProperties(['firstName', 'lastName', 'zipCode']); // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
```
@method getProperties
@param {String...|Array} list of keys to get

}
for(var i = 0; i < propertyNames.length; i++) {
ret[propertyNames[i]] = get(this, propertyNames[i]);
}
return ret;
},
/**
Sets the provided key or path to the value.
This method is generally very similar to calling `object[key] = value` or
`object.key = value`, except that it provides support for computed
properties, the `unknownProperty()` method and property observers.
### Computed Properties
If you try to set a value on a key that has a computed property handler
defined (see the `get()` method for an example), then `set()` will call
that method, passing both the value and key instead of simply changing
the value itself. This is useful for those times when you need to
implement a property that is composed of one or more member
properties.
### Unknown Properties
If you try to set a value on a key that is undefined in the target
object, then the `unknownProperty()` handler will be called instead. This
gives you an opportunity to implement complex "virtual" properties that
are not predefined on the object. If `unknownProperty()` returns
undefined, then `set()` will simply set the value on the object.
### Property Observers
In addition to changing the property, `set()` will also register a property
change with the object. Unless you have placed this call inside of a
`beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers
(i.e. observer methods declared on the same object), will be called
immediately. Any "remote" observers (i.e. observer methods declared on
another object) will be placed in a queue and called at a later time in a
coalesced manner.
### Chaining
In addition to property changes, `set()` returns the value of the object
itself so you can do chaining like this:
```javascript
record.set('firstName', 'Charles').set('lastName', 'Jolley');
```
@method set
@param {String} key The property to set
@param {Object} value The value to set or `null`.
@return {Ember.Observable}
*/
set: function(keyName, value) {
set(this, keyName, value);

/**

Adds an observer on a property.
This is the core method used to register an observer for a property.
Once you call this method, anytime the key's value is set, your observer
will be notified. Note that the observers are triggered anytime the
value is set, regardless of whether it has actually changed. Your
observer should be prepared to handle that.
You can also pass an optional context parameter to this method. The
context will be passed to your observer method whenever it is triggered.
Note that if you add the same target/method pair on a key multiple times
with different context parameters, your observer will only be called once
with the last context you passed.
### Observer Methods
Observer methods you pass should generally have the following signature if
you do not pass a `context` parameter:
```javascript
fooDidChange: function(sender, key, value, rev) { };
```
The sender is the object that changed. The key is the property that
changes. The value property is currently reserved and unused. The rev
is the last property revision of the object when it changed, which you can
use to detect if the key value has really changed or not.
If you pass a `context` parameter, the context will be passed before the
revision like so:
```javascript
fooDidChange: function(sender, key, value, context, rev) { };
```
Usually you will not need the value, context or revision parameters at
the end. In this case, it is common to write observer methods that take
only a sender and key value as parameters or, if you aren't interested in
any of these values, to write an observer that has no parameters at all.

/**
Defines the properties that will be concatenated from the superclass
(instead of overridden).
By default, when you extend an Ember class a property defined in
the subclass overrides a property with the same name that is defined
in the superclass. However, there are some cases where it is preferable
to build up a property's value by combining the superclass' property
value with the subclass' value. An example of this in use within Ember
is the `classNames` property of `Ember.View`.
Here is some sample code showing the difference between a concatenated
property and a normal one:
```javascript
App.BarView = Ember.View.extend({
someNonConcatenatedProperty: ['bar'],
classNames: ['bar']
});
App.FooBarView = App.BarView.extend({
someNonConcatenatedProperty: ['foo'],
classNames: ['foo'],
});
var fooBarView = App.FooBarView.create();
fooBarView.get('someNonConcatenatedProperty'); // ['foo']
fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo']
```
This behavior extends to object creation as well. Continuing the
above example:
```javascript
var view = App.FooBarView.create({
someNonConcatenatedProperty: ['baz'],
classNames: ['baz']
})
view.get('someNonConcatenatedProperty'); // ['baz']
view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
```
Adding a single property that is not an array will just add it in the array:
```javascript
var view = App.FooBarView.create({
classNames: 'baz'
})
view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
```
Using the `concatenatedProperties` property, we can tell to Ember that mix
the content of the properties.
In `Ember.View` the `classNameBindings` and `attributeBindings` properties
are also concatenated, in addition to `classNames`.
This feature is available for you to use throughout the Ember object model,
although typical app developers are likely to use it infrequently.

/**
An unordered collection of objects.
A Set works a bit like an array except that its items are not ordered. You
can create a set to efficiently test for membership for an object. You can
also iterate through a set just like an array, even accessing objects by
index, however there is no guarantee as to their order.
All Sets are observable via the Enumerable Observer API - which works
on any enumerable object including both Sets and Arrays.
## Creating a Set
You can create a set like you would most objects using
`new Ember.Set()`. Most new sets you create will be empty, but you can
also initialize the set with some content by passing an array or other
enumerable of objects to the constructor.
Finally, you can pass in an existing set and the set will be copied. You
can also create a copy of a set by calling `Ember.Set#copy()`.
```javascript
// creates a new empty set
var foundNames = new Ember.Set();
// creates a set with four names in it.
var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P
// creates a copy of the names set.
var namesCopy = new Ember.Set(names);
// same as above.
var anotherNamesCopy = names.copy();
```
## Adding/Removing Objects
You generally add or remove objects from a set using `add()` or
`remove()`. You can add any type of object including primitives such as
numbers, strings, and booleans.
Unlike arrays, objects can only exist one time in a set. If you call `add()`
on a set with the same object multiple times, the object will only be added
once. Likewise, calling `remove()` with the same object multiple times will
remove the object the first time and have no effect on future calls until
you add the object to the set again.
NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do
so will be ignored.
In addition to add/remove you can also call `push()`/`pop()`. Push behaves
just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary
object, remove it and return it. This is a good way to use a set as a job
queue when you don't care which order the jobs are executed in.
## Testing for an Object
To test for an object's presence in a set you simply call
`Ember.Set#contains()`.
## Observing changes
When using `Ember.Set`, you can observe the `"[]"` property to be
alerted whenever the content changes. You can also add an enumerable
observer to the set to be notified of specific objects that are added and
removed from the set. See `Ember.Enumerable` for more information on
enumerables.
This is often unhelpful. If you are filtering sets of objects, for instance,
it is very inefficient to re-filter all of the items each time the set
changes. It would be better if you could just adjust the filtered set based
on what was changed on the original set. The same issue applies to merging
sets, as well.
## Other Methods
`Ember.Set` primary implements other mixin APIs. For a complete reference
on the methods you will use with `Ember.Set`, please consult these mixins.
The most useful ones will be `Ember.Enumerable` and
`Ember.MutableEnumerable` which implement most of the common iterator
methods you are used to on Array.
Note that you can also use the `Ember.Copyable` and `Ember.Freezable`
APIs on `Ember.Set` as well. Once a set is frozen it can no longer be
modified. The benefit of this is that when you call `frozenCopy()` on it,
Ember will avoid making copies of the set. This allows you to write
code that can know with certainty when the underlying set data will or
will not be modified.

/**
`Ember.ArrayController` provides a way for you to publish a collection of
objects so that you can easily bind to the collection from a Handlebars
`#each` helper, an `Ember.CollectionView`, or other controllers.
The advantage of using an `ArrayController` is that you only have to set up
your view bindings once; to change what's displayed, simply swap out the
`content` property on the controller.
For example, imagine you wanted to display a list of items fetched via an XHR
request. Create an `Ember.ArrayController` and set its `content` property:
```javascript
MyApp.listController = Ember.ArrayController.create();
$.get('people.json', function(data) {
MyApp.listController.set('content', data);
});
```
Then, create a view that binds to your new controller:
```handlebars
{{#each MyApp.listController}}
{{firstName}} {{lastName}}
{{/each}}
```
Although you are binding to the controller, the behavior of this controller
is to pass through any methods or properties to the underlying array. This
capability comes from `Ember.ArrayProxy`, which this class inherits from.
Sometimes you want to display computed properties within the body of an
`#each` helper that depend on the underlying items in `content`, but are not
present on those items. To do this, set `itemController` to the name of a
controller (probably an `ObjectController`) that will wrap each individual item.
For example:
```handlebars
{{#each post in controller}}
<li>{{title}} ({{titleLength}} characters)</li>
{{/each}}
```
```javascript
App.PostsController = Ember.ArrayController.extend({
itemController: 'post'
});
App.PostController = Ember.ObjectController.extend({
// the `title` property will be proxied to the underlying post.
titleLength: function() {
return this.get('title').length;
}.property('title')
});
```
In some cases it is helpful to return a different `itemController` depending
on the particular item. Subclasses can do this by overriding
`lookupItemController`.
For example:
```javascript
App.MyArrayController = Ember.ArrayController.extend({
lookupItemController: function( object ) {
if (object.get('isSpecial')) {
return "special"; // use App.SpecialController
} else {
return "regular"; // use App.RegularController
}
}
});
```

/**
`Ember.View` is the class in Ember responsible for encapsulating templates of
HTML content, combining templates with data to render as sections of a page's
DOM, and registering and responding to user-initiated events.
## HTML Tag
The default HTML tag name used for a view's DOM representation is `div`. This
can be customized by setting the `tagName` property. The following view
class:
```javascript
ParagraphView = Ember.View.extend({
tagName: 'em'
});
```
Would result in instances with the following HTML:
```html
<em id="ember1" class="ember-view"></em>
```
## HTML `class` Attribute
The HTML `class` attribute of a view's tag can be set by providing a
`classNames` property that is set to an array of strings:
```javascript
MyView = Ember.View.extend({
classNames: ['my-class', 'my-other-class']
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view my-class my-other-class"></div>
```
`class` attribute values can also be set by providing a `classNameBindings`
property set to an array of properties names for the view. The return value
of these properties will be added as part of the value for the view's `class`
attribute. These properties can be computed properties:
```javascript
MyView = Ember.View.extend({
classNameBindings: ['propertyA', 'propertyB'],
propertyA: 'from-a',
propertyB: function(){
if(someLogic){ return 'from-b'; }
}.property()
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view from-a from-b"></div>
```
If the value of a class name binding returns a boolean the property name
itself will be used as the class name if the property is true. The class name
will not be added if the value is `false` or `undefined`.
```javascript
MyView = Ember.View.extend({
classNameBindings: ['hovered'],
hovered: true
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view hovered"></div>
```
When using boolean class name bindings you can supply a string value other
than the property name for use as the `class` HTML attribute by appending the
preferred value after a ":" character when defining the binding:
```javascript
MyView = Ember.View.extend({
classNameBindings: ['awesome:so-very-cool'],
awesome: true
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view so-very-cool"></div>
```
Boolean value class name bindings whose property names are in a
camelCase-style format will be converted to a dasherized format:
```javascript
MyView = Ember.View.extend({
classNameBindings: ['isUrgent'],
isUrgent: true
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view is-urgent"></div>
```
Class name bindings can also refer to object values that are found by
traversing a path relative to the view itself:
```javascript
MyView = Ember.View.extend({
classNameBindings: ['messages.empty']
messages: Ember.Object.create({
empty: true
})
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view empty"></div>
```
If you want to add a class name for a property which evaluates to true and
and a different class name if it evaluates to false, you can pass a binding
like this:
```javascript
// Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false
Ember.View.create({
classNameBindings: ['isEnabled:enabled:disabled']
isEnabled: true
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view enabled"></div>
```
When isEnabled is `false`, the resulting HTML reprensentation looks like
this:
```html
<div id="ember1" class="ember-view disabled"></div>
```
This syntax offers the convenience to add a class if a property is `false`:
```javascript
// Applies no class when isEnabled is true and class 'disabled' when isEnabled is false
Ember.View.create({
classNameBindings: ['isEnabled::disabled']
isEnabled: true
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view"></div>
```
When the `isEnabled` property on the view is set to `false`, it will result
in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view disabled"></div>
```
Updates to the the value of a class name binding will result in automatic
update of the HTML `class` attribute in the view's rendered HTML
representation. If the value becomes `false` or `undefined` the class name
will be removed.
Both `classNames` and `classNameBindings` are concatenated properties. See
`Ember.Object` documentation for more information about concatenated
properties.
## HTML Attributes
The HTML attribute section of a view's tag can be set by providing an
`attributeBindings` property set to an array of property names on the view.
The return value of these properties will be used as the value of the view's
HTML associated attribute:
```javascript
AnchorView = Ember.View.extend({
tagName: 'a',
attributeBindings: ['href'],
href: 'http://google.com'
});
```
Will result in view instances with an HTML representation of:
```html
<a id="ember1" class="ember-view" href="http://google.com"></a>
```
If the return value of an `attributeBindings` monitored property is a boolean
the property will follow HTML's pattern of repeating the attribute's name as
its value:
```javascript
MyTextInput = Ember.View.extend({
tagName: 'input',
attributeBindings: ['disabled'],
disabled: true
});
```
Will result in view instances with an HTML representation of:
```html
<input id="ember1" class="ember-view" disabled="disabled" />
```
`attributeBindings` can refer to computed properties:
```javascript
MyTextInput = Ember.View.extend({
tagName: 'input',
attributeBindings: ['disabled'],
disabled: function(){
if (someLogic) {
return true;
} else {
return false;
}
}.property()
});
```
Updates to the the property of an attribute binding will result in automatic
update of the HTML attribute in the view's rendered HTML representation.
`attributeBindings` is a concatenated property. See `Ember.Object`
documentation for more information about concatenated properties.
## Templates
The HTML contents of a view's rendered representation are determined by its
template. Templates can be any function that accepts an optional context
parameter and returns a string of HTML that will be inserted within the
view's tag. Most typically in Ember this function will be a compiled
`Ember.Handlebars` template.
```javascript
AView = Ember.View.extend({
template: Ember.Handlebars.compile('I am the template')
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view">I am the template</div>
```
Within an Ember application is more common to define a Handlebars templates as
part of a page:
```html
<script type='text/x-handlebars' data-template-name='some-template'>
Hello
</script>
```
And associate it by name using a view's `templateName` property:
```javascript
AView = Ember.View.extend({
templateName: 'some-template'
});
```
Using a value for `templateName` that does not have a Handlebars template
with a matching `data-template-name` attribute will throw an error.
Assigning a value to both `template` and `templateName` properties will throw
an error.
For views classes that may have a template later defined (e.g. as the block
portion of a `{{view}}` Handlebars helper call in another template or in
a subclass), you can provide a `defaultTemplate` property set to compiled
template function. If a template is not later provided for the view instance
the `defaultTemplate` value will be used:
```javascript
AView = Ember.View.extend({
defaultTemplate: Ember.Handlebars.compile('I was the default'),
template: null,
templateName: null
});
```
Will result in instances with an HTML representation of:
```html
<div id="ember1" class="ember-view">I was the default</div>
```
If a `template` or `templateName` is provided it will take precedence over
`defaultTemplate`:
```javascript
AView = Ember.View.extend({
defaultTemplate: Ember.Handlebars.compile('I was the default')
});
aView = AView.create({
template: Ember.Handlebars.compile('I was the template, not default')
});
```
Will result in the following HTML representation when rendered:
```html
<div id="ember1" class="ember-view">I was the template, not default</div>
```
## View Context
The default context of the compiled template is the view's controller:
```javascript
AView = Ember.View.extend({
template: Ember.Handlebars.compile('Hello {{excitedGreeting}}')
});
aController = Ember.Object.create({
firstName: 'Barry',
excitedGreeting: function(){
return this.get("content.firstName") + "!!!"
}.property()
});
aView = AView.create({
controller: aController,
});
```
Will result in an HTML representation of:
```html
<div id="ember1" class="ember-view">Hello Barry!!!</div>
```
A context can also be explicitly supplied through the view's `context`
property. If the view has neither `context` nor `controller` properties, the
`parentView`'s context will be used.
## Layouts
Views can have a secondary template that wraps their main template. Like
primary templates, layouts can be any function that accepts an optional
context parameter and returns a string of HTML that will be inserted inside
view's tag. Views whose HTML element is self closing (e.g. `<input />`)
cannot have a layout and this property will be ignored.
Most typically in Ember a layout will be a compiled `Ember.Handlebars`
template.
A view's layout can be set directly with the `layout` property or reference
an existing Handlebars template by name with the `layoutName` property.
A template used as a layout must contain a single use of the Handlebars
`{{yield}}` helper. The HTML contents of a view's rendered `template` will be
inserted at this location:
```javascript
AViewWithLayout = Ember.View.extend({
layout: Ember.Handlebars.compile("<div class='my-decorative-class'>{{yield}}</div>")
template: Ember.Handlebars.compile("I got wrapped"),
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view">
<div class="my-decorative-class">
I got wrapped
</div>
</div>
```
See `Handlebars.helpers.yield` for more information.
## Responding to Browser Events
Views can respond to user-initiated events in one of three ways: method
implementation, through an event manager, and through `{{action}}` helper use
in their template or layout.
### Method Implementation
Views can respond to user-initiated events by implementing a method that
matches the event name. A `jQuery.Event` object will be passed as the
argument to this method.
```javascript
AView = Ember.View.extend({
click: function(event){
// will be called when when an instance's
// rendered element is clicked
}
});
```
### Event Managers
Views can define an object as their `eventManager` property. This object can
then implement methods that match the desired event names. Matching events
that occur on the view's rendered HTML or the rendered HTML of any of its DOM
descendants will trigger this method. A `jQuery.Event` object will be passed
as the first argument to the method and an `Ember.View` object as the
second. The `Ember.View` will be the view whose rendered HTML was interacted
with. This may be the view with the `eventManager` property or one of its
descendent views.
```javascript
AView = Ember.View.extend({
eventManager: Ember.Object.create({
doubleClick: function(event, view){
// will be called when when an instance's
// rendered element or any rendering
// of this views's descendent
// elements is clicked
}
})
});
```
An event defined for an event manager takes precedence over events of the
same name handled through methods on the view.
```javascript
AView = Ember.View.extend({
mouseEnter: function(event){
// will never trigger.
},
eventManager: Ember.Object.create({
mouseEnter: function(event, view){
// takes presedence over AView#mouseEnter
}
})
});
```
Similarly a view's event manager will take precedence for events of any views
rendered as a descendent. A method name that matches an event name will not
be called if the view instance was rendered inside the HTML representation of
a view that has an `eventManager` property defined that handles events of the
name. Events not handled by the event manager will still trigger method calls
on the descendent.
```javascript
OuterView = Ember.View.extend({
template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"),
eventManager: Ember.Object.create({
mouseEnter: function(event, view){
// view might be instance of either
// OutsideView or InnerView depending on
// where on the page the user interaction occured
}
})
});
InnerView = Ember.View.extend({
click: function(event){
// will be called if rendered inside
// an OuterView because OuterView's
// eventManager doesn't handle click events
},
mouseEnter: function(event){
// will never be called if rendered inside
// an OuterView.
}
});
```
### Handlebars `{{action}}` Helper
See `Handlebars.helpers.action`.
### Event Names
Possible events names for any of the responding approaches described above
are:
Touch events:
* `touchStart`
* `touchMove`
* `touchEnd`
* `touchCancel`
Keyboard events
* `keyDown`
* `keyUp`
* `keyPress`
Mouse events
* `mouseDown`
* `mouseUp`
* `contextMenu`
* `click`
* `doubleClick`
* `mouseMove`
* `focusIn`
* `focusOut`
* `mouseEnter`
* `mouseLeave`
Form events:
* `submit`
* `change`
* `focusIn`
* `focusOut`
* `input`
HTML5 drag and drop events:
* `dragStart`
* `drag`
* `dragEnter`
* `dragLeave`
* `drop`
* `dragEnd`
## Handlebars `{{view}}` Helper
Other `Ember.View` instances can be included as part of a view's template by
using the `{{view}}` Handlebars helper. See `Handlebars.helpers.view` for
additional information.

/**
A `ContainerView` is an `Ember.View` subclass that implements `Ember.MutableArray`
allowing programatic management of its child views.
## Setting Initial Child Views
The initial array of child views can be set in one of two ways. You can
provide a `childViews` property at creation time that contains instance of
`Ember.View`:
```javascript
aContainer = Ember.ContainerView.create({
childViews: [Ember.View.create(), Ember.View.create()]
});
```
You can also provide a list of property names whose values are instances of
`Ember.View`:
```javascript
aContainer = Ember.ContainerView.create({
childViews: ['aView', 'bView', 'cView'],
aView: Ember.View.create(),
bView: Ember.View.create(),
cView: Ember.View.create()
});
```
The two strategies can be combined:
```javascript
aContainer = Ember.ContainerView.create({
childViews: ['aView', Ember.View.create()],
aView: Ember.View.create()
});
```
Each child view's rendering will be inserted into the container's rendered
HTML in the same order as its position in the `childViews` property.
## Adding and Removing Child Views
The container view implements `Ember.MutableArray` allowing programatic management of its child views.
To remove a view, pass that view into a `removeObject` call on the container view.
Given an empty `<body>` the following code
```javascript
aContainer = Ember.ContainerView.create({
classNames: ['the-container'],
childViews: ['aView', 'bView'],
aView: Ember.View.create({
template: Ember.Handlebars.compile("A")
}),
bView: Ember.View.create({
template: Ember.Handlebars.compile("B")
})
});
aContainer.appendTo('body');
```
Results in the HTML
```html
<div class="ember-view the-container">
<div class="ember-view">A</div>
<div class="ember-view">B</div>
</div>
```
Removing a view
```javascript
aContainer.toArray(); // [aContainer.aView, aContainer.bView]
aContainer.removeObject(aContainer.get('bView'));
aContainer.toArray(); // [aContainer.aView]
```
Will result in the following HTML
```html
<div class="ember-view the-container">
<div class="ember-view">A</div>
</div>
```
Similarly, adding a child view is accomplished by adding `Ember.View` instances to the
container view.
Given an empty `<body>` the following code
```javascript
aContainer = Ember.ContainerView.create({
classNames: ['the-container'],
childViews: ['aView', 'bView'],
aView: Ember.View.create({
template: Ember.Handlebars.compile("A")
}),
bView: Ember.View.create({
template: Ember.Handlebars.compile("B")
})
});
aContainer.appendTo('body');
```
Results in the HTML
```html
<div class="ember-view the-container">
<div class="ember-view">A</div>
<div class="ember-view">B</div>
</div>
```
Adding a view
```javascript
AnotherViewClass = Ember.View.extend({
template: Ember.Handlebars.compile("Another view")
});
aContainer.toArray(); // [aContainer.aView, aContainer.bView]
aContainer.pushObject(AnotherViewClass.create());
aContainer.toArray(); // [aContainer.aView, aContainer.bView, <AnotherViewClass instance>]
```
Will result in the following HTML
```html
<div class="ember-view the-container">
<div class="ember-view">A</div>
<div class="ember-view">B</div>
<div class="ember-view">Another view</div>
</div>
```
## Templates and Layout
A `template`, `templateName`, `defaultTemplate`, `layout`, `layoutName` or
`defaultLayout` property on a container view will not result in the template
or layout being rendered. The HTML contents of a `Ember.ContainerView`'s DOM
representation will only be the rendered HTML of its child views.
## Binding a View to Display
If you would like to display a single view in your ContainerView, you can set
its `currentView` property. When the `currentView` property is set to a view
instance, it will be added to the ContainerView. If the `currentView` property
is later changed to a different view, the new view will replace the old view.
If `currentView` is set to `null`, the last `currentView` will be removed.
This functionality is useful for cases where you want to bind the display of
a ContainerView to a controller or state manager. For example, you can bind
the `currentView` of a container to a controller like this:
```javascript
App.appController = Ember.Object.create({
view: Ember.View.create({
templateName: 'person_template'
})
});
```
```handlebars
{{view Ember.ContainerView currentViewBinding="App.appController.view"}}
```

`Ember.CollectionView` is an `Ember.View` descendent responsible for managing
a collection (an array or array-like object) by maintaing a child view object
and associated DOM representation for each item in the array and ensuring
that child views and their associated rendered HTML are updated when items in
the array are added, removed, or replaced.
## Setting content
The managed collection of objects is referenced as the `Ember.CollectionView`
instance's `content` property.
```javascript
someItemsView = Ember.CollectionView.create({
content: ['A', 'B','C']
})
```
The view for each item in the collection will have its `content` property set
to the item.
## Specifying itemViewClass
By default the view class for each item in the managed collection will be an
instance of `Ember.View`. You can supply a different class by setting the
`CollectionView`'s `itemViewClass` property.
Given an empty `<body>` and the following code:
```javascript
someItemsView = Ember.CollectionView.create({
classNames: ['a-collection'],
content: ['A','B','C'],
itemViewClass: Ember.View.extend({
template: Ember.Handlebars.compile("the letter: {{view.content}}")
})
});
someItemsView.appendTo('body');
```
Will result in the following HTML structure
```html
<div class="ember-view a-collection">
<div class="ember-view">the letter: A</div>
<div class="ember-view">the letter: B</div>
<div class="ember-view">the letter: C</div>
</div>
```
## Automatic matching of parent/child tagNames
Setting the `tagName` property of a `CollectionView` to any of
"ul", "ol", "table", "thead", "tbody", "tfoot", "tr", or "select" will result
in the item views receiving an appropriately matched `tagName` property.
Given an empty `<body>` and the following code:
```javascript
anUndorderedListView = Ember.CollectionView.create({
tagName: 'ul',
content: ['A','B','C'],
itemViewClass: Ember.View.extend({
template: Ember.Handlebars.compile("the letter: {{view.content}}")
})
});
anUndorderedListView.appendTo('body');
```
Will result in the following HTML structure
```html
<ul class="ember-view a-collection">
<li class="ember-view">the letter: A</li>
<li class="ember-view">the letter: B</li>
<li class="ember-view">the letter: C</li>
</ul>
```
Additional `tagName` pairs can be provided by adding to
`Ember.CollectionView.CONTAINER_MAP `
```javascript
Ember.CollectionView.CONTAINER_MAP['article'] = 'section'
```
## Programatic creation of child views
For cases where additional customization beyond the use of a single
`itemViewClass` or `tagName` matching is required CollectionView's
`createChildView` method can be overidden:
```javascript
CustomCollectionView = Ember.CollectionView.extend({
createChildView: function(viewClass, attrs) {
if (attrs.content.kind == 'album') {
viewClass = App.AlbumView;
} else {
viewClass = App.SongView;
}
this._super(viewClass, attrs);
}
});
```
## Empty View
You can provide an `Ember.View` subclass to the `Ember.CollectionView`
instance as its `emptyView` property. If the `content` property of a
`CollectionView` is set to `null` or an empty array, an instance of this view
will be the `CollectionView`s only child.
```javascript
aListWithNothing = Ember.CollectionView.create({
classNames: ['nothing']
content: null,
emptyView: Ember.View.extend({
template: Ember.Handlebars.compile("The collection is empty")
})
});
aListWithNothing.appendTo('body');
```
Will result in the following HTML structure
```html
<div class="ember-view nothing">
<div class="ember-view">
The collection is empty
</div>
</div>
```
## Adding and Removing items
The `childViews` property of a `CollectionView` should not be directly
manipulated. Instead, add, remove, replace items from its `content` property.
This will trigger appropriate changes to its rendered HTML.
## Use in templates via the `{{collection}}` `Ember.Handlebars` helper
`Ember.Handlebars` provides a helper specifically for adding
`CollectionView`s to templates. See `Ember.Handlebars.collection` for more
details

/**
Register a bound handlebars helper. Bound helpers behave similarly to regular
handlebars helpers, with the added ability to re-render when the underlying data
changes.
## Simple example
```javascript
Ember.Handlebars.registerBoundHelper('capitalize', function(value) {
return value.toUpperCase();
});
```
The above bound helper can be used inside of templates as follows:
```handlebars
{{capitalize name}}
```
In this case, when the `name` property of the template's context changes,
the rendered value of the helper will update to reflect this change.
## Example with options
Like normal handlebars helpers, bound helpers have access to the options
passed into the helper call.
```javascript
Ember.Handlebars.registerBoundHelper('repeat', function(value, options) {
var count = options.hash.count;
var a = [];
while(a.length < count){
a.push(value);
}
return a.join('');
});
```
This helper could be used in a template as follows:
```handlebars
{{repeat text count=3}}
```
## Example with bound options
Bound hash options are also supported. Example:
```handlebars
{{repeat text countBinding="numRepeats"}}
```
In this example, count will be bound to the value of
the `numRepeats` property on the context. If that property
changes, the helper will be re-rendered.
## Example with extra dependencies
The `Ember.Handlebars.registerBoundHelper` method takes a variable length
third parameter which indicates extra dependencies on the passed in value.
This allows the handlebars helper to update when these dependencies change.
```javascript
Ember.Handlebars.registerBoundHelper('capitalizeName', function(value) {
return value.get('name').toUpperCase();
}, 'name');
```
## Example with multiple bound properties
`Ember.Handlebars.registerBoundHelper` supports binding to
multiple properties, e.g.:
```javascript
Ember.Handlebars.registerBoundHelper('concatenate', function() {
var values = arguments[arguments.length - 1];
return values.join('||');
});
```
Which allows for template syntax such as {{concatenate prop1 prop2}} or
{{concatenate prop1 prop2 prop3}}. If any of the properties change,
the helpr will re-render. Note that dependency keys cannot be
using in conjunction with multi-property helpers, since it is ambiguous
which property the dependent keys would belong to.
## Use with unbound helper
The {{unbound}} helper can be used with bound helper invocations
to render them in their unbound form, e.g.
```handlebars
{{unbound capitalize name}}
```
In this example, if the name property changes, the helper
will not re-render.

`bindAttr` allows you to create a binding between DOM element attributes and
Ember objects. For example:
```handlebars
<img {{bindAttr src="imageUrl" alt="imageTitle"}}>
```
The above handlebars template will fill the `<img>`'s `src` attribute will
the value of the property referenced with `"imageUrl"` and its `alt`
attribute with the value of the property referenced with `"imageTitle"`.
If the rendering context of this template is the following object:
```javascript
{
imageUrl: 'http://lolcats.info/haz-a-funny',
imageTitle: 'A humorous image of a cat'
}
```
The resulting HTML output will be:
```html
<img src="http://lolcats.info/haz-a-funny" alt="A humorous image of a cat">
```
`bindAttr` cannot redeclare existing DOM element attributes. The use of `src`
in the following `bindAttr` example will be ignored and the hard coded value
of `src="/failwhale.gif"` will take precedence:
```handlebars
<img src="/failwhale.gif" {{bindAttr src="imageUrl" alt="imageTitle"}}>
```
### `bindAttr` and the `class` attribute
`bindAttr` supports a special syntax for handling a number of cases unique
to the `class` DOM element attribute. The `class` attribute combines
multiple discreet values into a single attribute as a space-delimited
list of strings. Each string can be:
* a string return value of an object's property.
* a boolean return value of an object's property
* a hard-coded value
A string return value works identically to other uses of `bindAttr`. The
return value of the property will become the value of the attribute. For
example, the following view and template:
```javascript
AView = Ember.View.extend({
someProperty: function(){
return "aValue";
}.property()
})
```
```handlebars
<img {{bindAttr class="view.someProperty}}>
```
Result in the following rendered output:
```html
<img class="aValue">
```
A boolean return value will insert a specified class name if the property
returns `true` and remove the class name if the property returns `false`.
A class name is provided via the syntax
`somePropertyName:class-name-if-true`.
```javascript
AView = Ember.View.extend({
someBool: true
})
```
```handlebars
<img {{bindAttr class="view.someBool:class-name-if-true"}}>
```
Result in the following rendered output:
```html
<img class="class-name-if-true">
```
An additional section of the binding can be provided if you want to
replace the existing class instead of removing it when the boolean
value changes:
```handlebars
<img {{bindAttr class="view.someBool:class-name-if-true:class-name-if-false"}}>
```
A hard-coded value can be used by prepending `:` to the desired
class name: `:class-name-to-always-apply`.
```handlebars
<img {{bindAttr class=":class-name-to-always-apply"}}>
```
Results in the following rendered output:
```html
<img class=":class-name-to-always-apply">
```
All three strategies - string return value, boolean return value, and
hard-coded value – can be combined in a single declaration:
```handlebars
<img {{bindAttr class=":class-name-to-always-apply view.someBool:class-name-if-true view.someProperty"}}>
```

/**
`{{view}}` inserts a new instance of `Ember.View` into a template passing its
options to the `Ember.View`'s `create` method and using the supplied block as
the view's own template.
An empty `<body>` and the following template:
```handlebars
A span:
{{#view tagName="span"}}
hello.
{{/view}}
```
Will result in HTML structure:
```html
<body>
<!-- Note: the handlebars template script
also results in a rendered Ember.View
which is the outer <div> here -->
<div class="ember-view">
A span:
<span id="ember1" class="ember-view">
Hello.
</span>
</div>
</body>
```
### `parentView` setting
The `parentView` property of the new `Ember.View` instance created through
`{{view}}` will be set to the `Ember.View` instance of the template where
`{{view}}` was called.
```javascript
aView = Ember.View.create({
template: Ember.Handlebars.compile("{{#view}} my parent: {{parentView.elementId}} {{/view}}")
});
aView.appendTo('body');
```
Will result in HTML structure:
```html
<div id="ember1" class="ember-view">
<div id="ember2" class="ember-view">
my parent: ember1
</div>
</div>
```
### Setting CSS id and class attributes
The HTML `id` attribute can be set on the `{{view}}`'s resulting element with
the `id` option. This option will _not_ be passed to `Ember.View.create`.
```handlebars
{{#view tagName="span" id="a-custom-id"}}
hello.
{{/view}}
```
Results in the following HTML structure:
```html
<div class="ember-view">
<span id="a-custom-id" class="ember-view">
hello.
</span>
</div>
```
The HTML `class` attribute can be set on the `{{view}}`'s resulting element
with the `class` or `classNameBindings` options. The `class` option will
directly set the CSS `class` attribute and will not be passed to
`Ember.View.create`. `classNameBindings` will be passed to `create` and use
`Ember.View`'s class name binding functionality:
```handlebars
{{#view tagName="span" class="a-custom-class"}}
hello.
{{/view}}
```
Results in the following HTML structure:
```html
<div class="ember-view">
<span id="ember2" class="ember-view a-custom-class">
hello.
</span>
</div>
```
### Supplying a different view class
`{{view}}` can take an optional first argument before its supplied options to
specify a path to a custom view class.
```handlebars
{{#view "MyApp.CustomView"}}
hello.
{{/view}}
```
The first argument can also be a relative path. Ember will search for the
view class starting at the `Ember.View` of the template where `{{view}}` was
used as the root object:
```javascript
MyApp = Ember.Application.create({});
MyApp.OuterView = Ember.View.extend({
innerViewClass: Ember.View.extend({
classNames: ['a-custom-view-class-as-property']
}),
template: Ember.Handlebars.compile('{{#view "innerViewClass"}} hi {{/view}}')
});
MyApp.OuterView.create().appendTo('body');
```
Will result in the following HTML:
```html
<div id="ember1" class="ember-view">
<div id="ember2" class="ember-view a-custom-view-class-as-property">
hi
</div>
</div>
```
### Blockless use
If you supply a custom `Ember.View` subclass that specifies its own template
or provide a `templateName` option to `{{view}}` it can be used without
supplying a block. Attempts to use both a `templateName` option and supply a
block will throw an error.
```handlebars
{{view "MyApp.ViewWithATemplateDefined"}}
```
### `viewName` property
You can supply a `viewName` option to `{{view}}`. The `Ember.View` instance
will be referenced as a property of its parent view by this name.
```javascript
aView = Ember.View.create({
template: Ember.Handlebars.compile('{{#view viewName="aChildByName"}} hi {{/view}}')
});
aView.appendTo('body');
aView.get('aChildByName') // the instance of Ember.View created by {{view}} helper
```

/**
`{{collection}}` is a `Ember.Handlebars` helper for adding instances of
`Ember.CollectionView` to a template. See `Ember.CollectionView` for
additional information on how a `CollectionView` functions.
`{{collection}}`'s primary use is as a block helper with a `contentBinding`
option pointing towards an `Ember.Array`-compatible object. An `Ember.View`
instance will be created for each item in its `content` property. Each view
will have its own `content` property set to the appropriate item in the
collection.
The provided block will be applied as the template for each item's view.
Given an empty `<body>` the following template:
```handlebars
{{#collection contentBinding="App.items"}}
Hi {{view.content.name}}
{{/collection}}
```
And the following application code
```javascript
App = Ember.Application.create()
App.items = [
Ember.Object.create({name: 'Dave'}),
Ember.Object.create({name: 'Mary'}),
Ember.Object.create({name: 'Sara'})
]
```
Will result in the HTML structure below
```html
<div class="ember-view">
<div class="ember-view">Hi Dave</div>
<div class="ember-view">Hi Mary</div>
<div class="ember-view">Hi Sara</div>
</div>
```
### Blockless Use
If you provide an `itemViewClass` option that has its own `template` you can
omit the block.
The following template:
```handlebars
{{collection contentBinding="App.items" itemViewClass="App.AnItemView"}}
```
And application code
```javascript
App = Ember.Application.create();
App.items = [
Ember.Object.create({name: 'Dave'}),
Ember.Object.create({name: 'Mary'}),
Ember.Object.create({name: 'Sara'})
];
App.AnItemView = Ember.View.extend({
template: Ember.Handlebars.compile("Greetings {{view.content.name}}")
});
```
Will result in the HTML structure below
```html
<div class="ember-view">
<div class="ember-view">Greetings Dave</div>
<div class="ember-view">Greetings Mary</div>
<div class="ember-view">Greetings Sara</div>
</div>
```
### Specifying a CollectionView subclass
By default the `{{collection}}` helper will create an instance of
`Ember.CollectionView`. You can supply a `Ember.CollectionView` subclass to
the helper by passing it as the first argument:
```handlebars
{{#collection App.MyCustomCollectionClass contentBinding="App.items"}}
Hi {{view.content.name}}
{{/collection}}
```
### Forwarded `item.*`-named Options
As with the `{{view}}`, helper options passed to the `{{collection}}` will be
set on the resulting `Ember.CollectionView` as properties. Additionally,
options prefixed with `item` will be applied to the views rendered for each
item (note the camelcasing):
```handlebars
{{#collection contentBinding="App.items"
itemTagName="p"
itemClassNames="greeting"}}
Howdy {{view.content.name}}
{{/collection}}
```
Will result in the following HTML structure:
```html
<div class="ember-view">
<p class="ember-view greeting">Howdy Dave</p>
<p class="ember-view greeting">Howdy Mary</p>
<p class="ember-view greeting">Howdy Sara</p>
</div>
```

/**
The `{{#each}}` helper loops over elements in a collection, rendering its
block once for each item. It is an extension of the base Handlebars `{{#each}}`
helper:
```javascript
Developers = [{name: 'Yehuda'},{name: 'Tom'}, {name: 'Paul'}];
```
```handlebars
{{#each Developers}}
{{name}}
{{/each}}
```
`{{each}}` supports an alternative syntax with element naming:
```handlebars
{{#each person in Developers}}
{{person.name}}
{{/each}}
```
When looping over objects that do not have properties, `{{this}}` can be used
to render the object:
```javascript
DeveloperNames = ['Yehuda', 'Tom', 'Paul']
```
```handlebars
{{#each DeveloperNames}}
{{this}}
{{/each}}
```
### {{else}} condition
`{{#each}}` can have a matching `{{else}}`. The contents of this block will render
if the collection is empty.
```
{{#each person in Developers}}
{{person.name}}
{{else}}
<p>Sorry, nobody is available for this task.</p>
{{/each}}
```
### Specifying a View class for items
If you provide an `itemViewClass` option that references a view class
with its own `template` you can omit the block.
The following template:
```handlebars
{{#view App.MyView }}
{{each view.items itemViewClass="App.AnItemView"}}
{{/view}}
```
And application code
```javascript
App = Ember.Application.create({
MyView: Ember.View.extend({
items: [
Ember.Object.create({name: 'Dave'}),
Ember.Object.create({name: 'Mary'}),
Ember.Object.create({name: 'Sara'})
]
})
});
App.AnItemView = Ember.View.extend({
template: Ember.Handlebars.compile("Greetings {{name}}")
});
```
Will result in the HTML structure below
```html
<div class="ember-view">
<div class="ember-view">Greetings Dave</div>
<div class="ember-view">Greetings Mary</div>
<div class="ember-view">Greetings Sara</div>
</div>
```
### Representing each item with a Controller.
By default the controller lookup within an `{{#each}}` block will be
the controller of the template where the `{{#each}}` was used. If each
item needs to be presented by a custom controller you can provide a
`itemController` option which references a controller by lookup name.
Each item in the loop will be wrapped in an instance of this controller
and the item itself will be set to the `content` property of that controller.
This is useful in cases where properties of model objects need transformation
or synthesis for display:
```javascript
App.DeveloperController = Ember.ObjectController.extend({
isAvailableForHire: function(){
return !this.get('content.isEmployed') && this.get('content.isSeekingWork');
}.property('isEmployed', 'isSeekingWork')
})
```
```handlebars
{{#each person in Developers itemController="developer"}}
{{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}}
{{/each}}
```

`template` allows you to render a template from inside another template.
This allows you to re-use the same template in multiple places. For example:
```html
<script type="text/x-handlebars" data-template-name="logged_in_user">
{{#with loggedInUser}}
Last Login: {{lastLogin}}
User Info: {{template "user_info"}}
{{/with}}
</script>
```
```html
<script type="text/x-handlebars" data-template-name="user_info">
Name: <em>{{name}}</em>
Karma: <em>{{karma}}</em>
</script>
```
This helper looks for templates in the global `Ember.TEMPLATES` hash. If you
add `<script>` tags to your page with the `data-template-name` attribute set,
they will be compiled and placed in this hash automatically.
You can also manually register templates by adding them to the hash:
```javascript
Ember.TEMPLATES["my_cool_template"] = Ember.Handlebars.compile('<b>{{user}}</b>');
```

@param {String} templateName the template to render

/**
The `Ember.Select` view class renders a
[select](https://developer.mozilla.org/en/HTML/Element/select) HTML element,
allowing the user to choose from a list of options.
The text and `value` property of each `<option>` element within the
`<select>` element are populated from the objects in the `Element.Select`'s
`content` property. The underlying data object of the selected `<option>` is
stored in the `Element.Select`'s `value` property.
### `content` as an array of Strings
The simplest version of an `Ember.Select` takes an array of strings as its
`content` property. The string will be used as both the `value` property and
the inner text of each `<option>` element inside the rendered `<select>`.
Example:
```javascript
App.names = ["Yehuda", "Tom"];
```
```handlebars
{{view Ember.Select contentBinding="App.names"}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option value="Yehuda">Yehuda</option>
<option value="Tom">Tom</option>
</select>
```
You can control which `<option>` is selected through the `Ember.Select`'s
`value` property directly or as a binding:
```javascript
App.names = Ember.Object.create({
selected: 'Tom',
content: ["Yehuda", "Tom"]
});
```
```handlebars
{{view Ember.Select
contentBinding="App.names.content"
valueBinding="App.names.selected"
}}
```
Would result in the following HTML with the `<option>` for 'Tom' selected:
```html
<select class="ember-select">
<option value="Yehuda">Yehuda</option>
<option value="Tom" selected="selected">Tom</option>
</select>
```
A user interacting with the rendered `<select>` to choose "Yehuda" would
update the value of `App.names.selected` to "Yehuda".
### `content` as an Array of Objects
An `Ember.Select` can also take an array of JavaScript or Ember objects as
its `content` property.
When using objects you need to tell the `Ember.Select` which property should
be accessed on each object to supply the `value` attribute of the `<option>`
and which property should be used to supply the element text.
The `optionValuePath` option is used to specify the path on each object to
the desired property for the `value` attribute. The `optionLabelPath`
specifies the path on each object to the desired property for the
element's text. Both paths must reference each object itself as `content`:
```javascript
App.programmers = [
Ember.Object.create({firstName: "Yehuda", id: 1}),
Ember.Object.create({firstName: "Tom", id: 2})
];
```
```handlebars
{{view Ember.Select
contentBinding="App.programmers"
optionValuePath="content.id"
optionLabelPath="content.firstName"}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option value>Please Select</option>
<option value="1">Yehuda</option>
<option value="2">Tom</option>
</select>
```
The `value` attribute of the selected `<option>` within an `Ember.Select`
can be bound to a property on another object by providing a
`valueBinding` option:
```javascript
App.programmers = [
Ember.Object.create({firstName: "Yehuda", id: 1}),
Ember.Object.create({firstName: "Tom", id: 2})
];
App.currentProgrammer = Ember.Object.create({
id: 2
});
```
```handlebars
{{view Ember.Select
contentBinding="App.programmers"
optionValuePath="content.id"
optionLabelPath="content.firstName"
valueBinding="App.currentProgrammer.id"}}
```
Would result in the following HTML with a selected option:
```html
<select class="ember-select">
<option value>Please Select</option>
<option value="1">Yehuda</option>
<option value="2" selected="selected">Tom</option>
</select>
```
Interacting with the rendered element by selecting the first option
('Yehuda') will update the `id` value of `App.currentProgrammer`
to match the `value` property of the newly selected `<option>`.
Alternatively, you can control selection through the underlying objects
used to render each object providing a `selectionBinding`. When the selected
`<option>` is changed, the property path provided to `selectionBinding`
will be updated to match the content object of the rendered `<option>`
element:
```javascript
App.controller = Ember.Object.create({
selectedPerson: null,
content: [
Ember.Object.create({firstName: "Yehuda", id: 1}),
Ember.Object.create({firstName: "Tom", id: 2})
]
});
```
```handlebars
{{view Ember.Select
contentBinding="App.controller.content"
optionValuePath="content.id"
optionLabelPath="content.firstName"
selectionBinding="App.controller.selectedPerson"}}
```
Would result in the following HTML with a selected option:
```html
<select class="ember-select">
<option value>Please Select</option>
<option value="1">Yehuda</option>
<option value="2" selected="selected">Tom</option>
</select>
```
Interacting with the rendered element by selecting the first option
('Yehuda') will update the `selectedPerson` value of `App.controller`
to match the content object of the newly selected `<option>`. In this
case it is the first object in the `App.content.content`
### Supplying a Prompt
A `null` value for the `Ember.Select`'s `value` or `selection` property
results in there being no `<option>` with a `selected` attribute:
```javascript
App.controller = Ember.Object.create({
selected: null,
content: [
"Yehuda",
"Tom"
]
});
```
``` handlebars
{{view Ember.Select
contentBinding="App.controller.content"
valueBinding="App.controller.selected"
}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option value="Yehuda">Yehuda</option>
<option value="Tom">Tom</option>
</select>
```
Although `App.controller.selected` is `null` and no `<option>`
has a `selected` attribute the rendered HTML will display the
first item as though it were selected. You can supply a string
value for the `Ember.Select` to display when there is no selection
with the `prompt` option:
```javascript
App.controller = Ember.Object.create({
selected: null,
content: [
"Yehuda",
"Tom"
]
});
```
```handlebars
{{view Ember.Select
contentBinding="App.controller.content"
valueBinding="App.controller.selected"
prompt="Please select a name"
}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option>Please select a name</option>
<option value="Yehuda">Yehuda</option>
<option value="Tom">Tom</option>
</select>
```

into handlers, and then figures out what to do with each of the handlers.
For example, consider the following tree of handlers. Each handler is
followed by the URL segment it handles.
```
|~index ("/")
| |~posts ("/posts")
| | |-showPost ("/:id")
| | |-newPost ("/new")
| | |-editPost ("/edit")
| |~about ("/about/:id")

1. A URL transition to `/posts/1`.
1. Triggers the `deserialize` callback on the
`index`, `posts`, and `showPost` handlers
2. Triggers the `enter` callback on the same
3. Triggers the `setup` callback on the same
2. A direct transition to `newPost`
1. Triggers the `exit` callback on `showPost`
2. Triggers the `enter` callback on `newPost`
3. Triggers the `setup` callback on `newPost`
3. A direct transition to `about` with a specified
context object
1. Triggers the `exit` callback on `newPost`
and `posts`
2. Triggers the `serialize` callback on `about`
3. Triggers the `enter` callback on `about`
4. Triggers the `setup` callback on `about`

/**
The `{{action}}` helper registers an HTML element within a template for DOM
event handling and forwards that interaction to the view's controller
or supplied `target` option (see 'Specifying a Target').
If the view's controller does not implement the event, the event is sent
to the current route, and it bubbles up the route hierarchy from there.
User interaction with that element will invoke the supplied action name on
the appropriate target.
Given the following Handlebars template on the page
```handlebars
<script type="text/x-handlebars" data-template-name='a-template'>
<div {{action anActionName}}>
click me
</div>
</script>
```
And application code
```javascript
AController = Ember.Controller.extend({
anActionName: function() {}
});
AView = Ember.View.extend({
controller: AController.create(),
templateName: 'a-template'
});
aView = AView.create();
aView.appendTo('body');
```
Will results in the following rendered HTML
```html
<div class="ember-view">
<div data-ember-action="1">
click me
</div>
</div>
```
Clicking "click me" will trigger the `anActionName` method of the
`AController`. In this case, no additional parameters will be passed.
If you provide additional parameters to the helper:
```handlebars
<button {{action 'edit' post}}>Edit</button>
```
Those parameters will be passed along as arguments to the JavaScript
function implementing the action.
### Event Propagation
Events triggered through the action helper will automatically have
`.preventDefault()` called on them. You do not need to do so in your event
handlers.
To also disable bubbling, pass `bubbles=false` to the helper:
```handlebars
<button {{action 'edit' post bubbles=false}}>Edit</button>
```
If you need the default handler to trigger you should either register your
own event handler, or use event methods on your view class. See `Ember.View`
'Responding to Browser Events' for more information.
### Specifying DOM event type
By default the `{{action}}` helper registers for DOM `click` events. You can
supply an `on` option to the helper to specify a different DOM event name:
```handlebars
<script type="text/x-handlebars" data-template-name='a-template'>
<div {{action anActionName on="doubleClick"}}>
click me
</div>
</script>
```
See `Ember.View` 'Responding to Browser Events' for a list of
acceptable DOM event names.
NOTE: Because `{{action}}` depends on Ember's event dispatch system it will
only function if an `Ember.EventDispatcher` instance is available. An
`Ember.EventDispatcher` instance will be created when a new `Ember.Application`
is created. Having an instance of `Ember.Application` will satisfy this
requirement.
### Specifying a Target
There are several possible target objects for `{{action}}` helpers:
In a typical Ember application, where views are managed through use of the
`{{outlet}}` helper, actions will bubble to the current controller, then
to the current route, and then up the route hierarchy.
Alternatively, a `target` option can be provided to the helper to change
which object will receive the method call. This option must be a path
path to an object, accessible in the current context:
```handlebars
<script type="text/x-handlebars" data-template-name='a-template'>
<div {{action anActionName target="MyApplication.someObject"}}>
click me
</div>
</script>
```
Clicking "click me" in the rendered HTML of the above template will trigger
the `anActionName` method of the object at `MyApplication.someObject`.
If an action's target does not implement a method that matches the supplied
action name an error will be thrown.
```handlebars
<script type="text/x-handlebars" data-template-name='a-template'>
<div {{action aMethodNameThatIsMissing}}>
click me
</div>
</script>
```
With the following application code
```javascript
AView = Ember.View.extend({
templateName; 'a-template',
// note: no method 'aMethodNameThatIsMissing'
anActionName: function(event) {}
});
aView = AView.create();
aView.appendTo('body');
```
Will throw `Uncaught TypeError: Cannot call method 'call' of undefined` when
"click me" is clicked.
### Additional Parameters
You may specify additional parameters to the `{{action}}` helper. These
parameters are passed along as the arguments to the JavaScript function
implementing the action.
```handlebars
<script type="text/x-handlebars" data-template-name='a-template'>
{{#each person in people}}
<div {{action edit person}}>
click me
</div>
{{/each}}
</script>
```
Clicking "click me" will trigger the `edit` method on the current view's
controller with the current person as a parameter.

/**
An instance of `Ember.Application` is the starting point for every Ember
application. It helps to instantiate, initialize and coordinate the many
objects that make up your app.
Each Ember app has one and only one `Ember.Application` object. In fact, the
very first thing you should do in your application is create the instance:
```javascript
window.App = Ember.Application.create();
```
Typically, the application object is the only global variable. All other
classes in your app should be properties on the `Ember.Application` instance,
which highlights its first role: a global namespace.
For example, if you define a view class, it might look like this:
```javascript
App.MyView = Ember.View.extend();
```
By default, calling `Ember.Application.create()` will automatically initialize
your application by calling the `Ember.Application.initialize()` method. If
you need to delay initialization, you can call your app's `deferReadiness()`
method. When you are ready for your app to be initialized, call its
`advanceReadiness()` method.
Because `Ember.Application` inherits from `Ember.Namespace`, any classes
you create will have useful string representations when calling `toString()`.
See the `Ember.Namespace` documentation for more information.
While you can think of your `Ember.Application` as a container that holds the
other classes in your application, there are several other responsibilities
going on under-the-hood that you may want to understand.
### Event Delegation
Ember uses a technique called _event delegation_. This allows the framework
to set up a global, shared event listener instead of requiring each view to
do it manually. For example, instead of each view registering its own
`mousedown` listener on its associated element, Ember sets up a `mousedown`
listener on the `body`.
If a `mousedown` event occurs, Ember will look at the target of the event and
start walking up the DOM node tree, finding corresponding views and invoking
their `mouseDown` method as it goes.
`Ember.Application` has a number of default events that it listens for, as
well as a mapping from lowercase events to camel-cased view method names. For
example, the `keypress` event causes the `keyPress` method on the view to be
called, the `dblclick` event causes `doubleClick` to be called, and so on.
If there is a browser event that Ember does not listen for by default, you
can specify custom events and their corresponding view method names by
setting the application's `customEvents` property:
```javascript
App = Ember.Application.create({
customEvents: {
// add support for the loadedmetadata media
// player event
'loadedmetadata': "loadedMetadata"
}
});
```
By default, the application sets up these event listeners on the document
body. However, in cases where you are embedding an Ember application inside
an existing page, you may want it to set up the listeners on an element
inside the body.
For example, if only events inside a DOM element with the ID of `ember-app`
should be delegated, set your application's `rootElement` property:
```javascript
window.App = Ember.Application.create({
rootElement: '#ember-app'
});
```
The `rootElement` can be either a DOM element or a jQuery-compatible selector
string. Note that *views appended to the DOM outside the root element will
not receive events.* If you specify a custom root element, make sure you only
append views inside it!
To learn more about the advantages of event delegation and the Ember view
layer, and a list of the event listeners that are setup by default, visit the
[Ember View Layer guide](http://emberjs.com/guides/view_layer#toc_event-delegation).
### Initializers
Libraries on top of Ember can register additional initializers, like so:
```javascript
Ember.Application.initializer({
name: "store",
initialize: function(container, application) {
container.register('store', 'main', application.Store);
}
});
```
### Routing
In addition to creating your application's router, `Ember.Application` is
also responsible for telling the router when to start routing.
By default, the router will begin trying to translate the current URL into
application state once the browser emits the `DOMContentReady` event. If you
need to defer routing, you can call the application's `deferReadiness()`
method. Once routing can begin, call the `advanceReadiness()` method.
If there is any setup required before routing begins, you can implement a
`ready()` method on your app that will be invoked immediately before routing
begins:
```javascript
window.App = Ember.Application.create({
ready: function() {
this.set('router.enableLogging', true);
}
});
To begin routing, you must have at a minimum a top-level controller and view.
You define these as `App.ApplicationController` and `App.ApplicationView`,
respectively. Your application will not work if you do not define these two
mandatory classes. For example:
```javascript
App.ApplicationView = Ember.View.extend({
templateName: 'application'
});
App.ApplicationController = Ember.Controller.extend();
```
@class Application
@namespace Ember
@extends Ember.Namespace
*/
var Application = Ember.Application = Ember.Namespace.extend(
/** @scope Ember.Application.prototype */{
/**
The root DOM element of the Application. This can be specified as an
element or a

view in your application should be a child of the element you specify here.

By default, the application's `Ember.EventDispatcher` listens
for a set of standard DOM events, such as `mousedown` and
`keyup`, and delegates them to your application's `Ember.View`
instances.
If you would like additional events to be delegated to your
views, set your `Ember.Application`'s `customEvents` property
to a hash containing the DOM event name as the key and the
corresponding view method name as the value. For example:
```javascript
App = Ember.Application.create({
customEvents: {
// add support for the loadedmetadata media
// player event
'loadedmetadata': "loadedMetadata"
}
});
```

/**
StateManager is part of Ember's implementation of a finite state machine. A
StateManager instance manages a number of properties that are instances of
`Ember.State`,
tracks the current active state, and triggers callbacks when states have changed.
## Defining States
The states of StateManager can be declared in one of two ways. First, you can
define a `states` property that contains all the states:
```javascript
managerA = Ember.StateManager.create({
states: {
stateOne: Ember.State.create(),
stateTwo: Ember.State.create()
}
})
managerA.get('states')
// {
// stateOne: Ember.State.create(),
// stateTwo: Ember.State.create()
// }
```
You can also add instances of `Ember.State` (or an `Ember.State` subclass)
directly as properties of a StateManager. These states will be collected into
the `states` property for you.
```javascript
managerA = Ember.StateManager.create({
stateOne: Ember.State.create(),
stateTwo: Ember.State.create()
})
managerA.get('states')
// {
// stateOne: Ember.State.create(),
// stateTwo: Ember.State.create()
// }
```
## The Initial State
When created a StateManager instance will immediately enter into the state
defined as its `start` property or the state referenced by name in its
`initialState` property:
```javascript
managerA = Ember.StateManager.create({
start: Ember.State.create({})
})
managerA.get('currentState.name') // 'start'
managerB = Ember.StateManager.create({
initialState: 'beginHere',
beginHere: Ember.State.create({})
})
managerB.get('currentState.name') // 'beginHere'
```
Because it is a property you may also provide a computed function if you wish
to derive an `initialState` programmatically:
```javascript
managerC = Ember.StateManager.create({
initialState: function(){
if (someLogic) {
return 'active';
} else {
return 'passive';
}
}.property(),
active: Ember.State.create({}),
passive: Ember.State.create({})
})
```
## Moving Between States
A StateManager can have any number of `Ember.State` objects as properties
and can have a single one of these states as its current state.
Calling `transitionTo` transitions between states:
```javascript
robotManager = Ember.StateManager.create({
initialState: 'poweredDown',
poweredDown: Ember.State.create({}),
poweredUp: Ember.State.create({})
})
robotManager.get('currentState.name') // 'poweredDown'
robotManager.transitionTo('poweredUp')
robotManager.get('currentState.name') // 'poweredUp'
```
Before transitioning into a new state the existing `currentState` will have
its `exit` method called with the StateManager instance as its first argument
and an object representing the transition as its second argument.
After transitioning into a new state the new `currentState` will have its
`enter` method called with the StateManager instance as its first argument
and an object representing the transition as its second argument.
```javascript
robotManager = Ember.StateManager.create({
initialState: 'poweredDown',
poweredDown: Ember.State.create({
exit: function(stateManager){
console.log("exiting the poweredDown state")
}
}),
poweredUp: Ember.State.create({
enter: function(stateManager){
console.log("entering the poweredUp state. Destroy all humans.")
}
})
})
robotManager.get('currentState.name') // 'poweredDown'
robotManager.transitionTo('poweredUp')
// will log
// 'exiting the poweredDown state'
// 'entering the poweredUp state. Destroy all humans.'
```
Once a StateManager is already in a state, subsequent attempts to enter that
state will not trigger enter or exit method calls. Attempts to transition
into a state that the manager does not have will result in no changes in the
StateManager's current state:
```javascript
robotManager = Ember.StateManager.create({
initialState: 'poweredDown',
poweredDown: Ember.State.create({
exit: function(stateManager){
console.log("exiting the poweredDown state")
}
}),
poweredUp: Ember.State.create({
enter: function(stateManager){
console.log("entering the poweredUp state. Destroy all humans.")
}
})
})
robotManager.get('currentState.name') // 'poweredDown'
robotManager.transitionTo('poweredUp')
// will log
// 'exiting the poweredDown state'
// 'entering the poweredUp state. Destroy all humans.'
robotManager.transitionTo('poweredUp') // no logging, no state change
robotManager.transitionTo('someUnknownState') // silently fails
robotManager.get('currentState.name') // 'poweredUp'
```
Each state property may itself contain properties that are instances of
`Ember.State`. The StateManager can transition to specific sub-states in a
series of transitionTo method calls or via a single transitionTo with the
full path to the specific state. The StateManager will also keep track of the
full path to its currentState
```javascript
robotManager = Ember.StateManager.create({
initialState: 'poweredDown',
poweredDown: Ember.State.create({
charging: Ember.State.create(),
charged: Ember.State.create()
}),
poweredUp: Ember.State.create({
mobile: Ember.State.create(),
stationary: Ember.State.create()
})
})
robotManager.get('currentState.name') // 'poweredDown'
robotManager.transitionTo('poweredUp')
robotManager.get('currentState.name') // 'poweredUp'
robotManager.transitionTo('mobile')
robotManager.get('currentState.name') // 'mobile'
// transition via a state path
robotManager.transitionTo('poweredDown.charging')
robotManager.get('currentState.name') // 'charging'
robotManager.get('currentState.path') // 'poweredDown.charging'
```
Enter transition methods will be called for each state and nested child state
in their hierarchical order. Exit methods will be called for each state and
its nested states in reverse hierarchical order.
Exit transitions for a parent state are not called when entering into one of
its child states, only when transitioning to a new section of possible states
in the hierarchy.
```javascript
robotManager = Ember.StateManager.create({
initialState: 'poweredDown',
poweredDown: Ember.State.create({
enter: function(){},
exit: function(){
console.log("exited poweredDown state")
},
charging: Ember.State.create({
enter: function(){},
exit: function(){}
}),
charged: Ember.State.create({
enter: function(){
console.log("entered charged state")
},
exit: function(){
console.log("exited charged state")
}
})
}),
poweredUp: Ember.State.create({
enter: function(){
console.log("entered poweredUp state")
},
exit: function(){},
mobile: Ember.State.create({
enter: function(){
console.log("entered mobile state")
},
exit: function(){}
}),
stationary: Ember.State.create({
enter: function(){},
exit: function(){}
})
})
})
robotManager.get('currentState.path') // 'poweredDown'
robotManager.transitionTo('charged')
// logs 'entered charged state'
// but does *not* log 'exited poweredDown state'
robotManager.get('currentState.name') // 'charged
robotManager.transitionTo('poweredUp.mobile')
// logs
// 'exited charged state'
// 'exited poweredDown state'
// 'entered poweredUp state'
// 'entered mobile state'
```
During development you can set a StateManager's `enableLogging` property to
`true` to receive console messages of state transitions.
```javascript
robotManager = Ember.StateManager.create({
enableLogging: true
})
```
## Managing currentState with Actions
To control which transitions are possible for a given state, and
appropriately handle external events, the StateManager can receive and
route action messages to its states via the `send` method. Calling to
`send` with an action name will begin searching for a method with the same
name starting at the current state and moving up through the parent states
in a state hierarchy until an appropriate method is found or the StateManager
instance itself is reached.
If an appropriately named method is found it will be called with the state
manager as the first argument and an optional `context` object as the second
argument.
```javascript
managerA = Ember.StateManager.create({
initialState: 'stateOne.substateOne.subsubstateOne',
stateOne: Ember.State.create({
substateOne: Ember.State.create({
anAction: function(manager, context){
console.log("an action was called")
},
subsubstateOne: Ember.State.create({})
})
})
})
managerA.get('currentState.name') // 'subsubstateOne'
managerA.send('anAction')
// 'stateOne.substateOne.subsubstateOne' has no anAction method
// so the 'anAction' method of 'stateOne.substateOne' is called
// and logs "an action was called"
// with managerA as the first argument
// and no second argument
someObject = {}
managerA.send('anAction', someObject)
// the 'anAction' method of 'stateOne.substateOne' is called again
// with managerA as the first argument and
// someObject as the second argument.
```
If the StateManager attempts to send an action but does not find an appropriately named
method in the current state or while moving upwards through the state hierarchy, it will
repeat the process looking for a `unhandledEvent` method. If an `unhandledEvent` method is
found, it will be called with the original event name as the second argument. If an
`unhandledEvent` method is not found, the StateManager will throw a new Ember.Error.
```javascript
managerB = Ember.StateManager.create({
initialState: 'stateOne.substateOne.subsubstateOne',
stateOne: Ember.State.create({
substateOne: Ember.State.create({
subsubstateOne: Ember.State.create({}),
unhandledEvent: function(manager, eventName, context) {
console.log("got an unhandledEvent with name " + eventName);
}
})
})
})
managerB.get('currentState.name') // 'subsubstateOne'
managerB.send('anAction')
// neither `stateOne.substateOne.subsubstateOne` nor any of it's
// parent states have a handler for `anAction`. `subsubstateOne`
// also does not have a `unhandledEvent` method, but its parent
// state, `substateOne`, does, and it gets fired. It will log
// "got an unhandledEvent with name anAction"
```
Action detection only moves upwards through the state hierarchy from the current state.
It does not search in other portions of the hierarchy.
```javascript
managerC = Ember.StateManager.create({
initialState: 'stateOne.substateOne.subsubstateOne',
stateOne: Ember.State.create({
substateOne: Ember.State.create({
subsubstateOne: Ember.State.create({})
})
}),
stateTwo: Ember.State.create({
anAction: function(manager, context){
// will not be called below because it is
// not a parent of the current state
}
})
})
managerC.get('currentState.name') // 'subsubstateOne'
managerC.send('anAction')
// Error: <Ember.StateManager:ember132> could not
// respond to event anAction in state stateOne.substateOne.subsubstateOne.
```
Inside of an action method the given state should delegate `transitionTo` calls on its
StateManager.
```javascript
robotManager = Ember.StateManager.create({
initialState: 'poweredDown.charging',
poweredDown: Ember.State.create({
charging: Ember.State.create({
chargeComplete: function(manager, context){
manager.transitionTo('charged')
}
}),
charged: Ember.State.create({
boot: function(manager, context){
manager.transitionTo('poweredUp')
}
})
}),
poweredUp: Ember.State.create({
beginExtermination: function(manager, context){
manager.transitionTo('rampaging')
},
rampaging: Ember.State.create()
})
})
robotManager.get('currentState.name') // 'charging'
robotManager.send('boot') // throws error, no boot action
// in current hierarchy
robotManager.get('currentState.name') // remains 'charging'
robotManager.send('beginExtermination') // throws error, no beginExtermination
// action in current hierarchy
robotManager.get('currentState.name') // remains 'charging'
robotManager.send('chargeComplete')
robotManager.get('currentState.name') // 'charged'
robotManager.send('boot')
robotManager.get('currentState.name') // 'poweredUp'
robotManager.send('beginExtermination', allHumans)
robotManager.get('currentState.name') // 'rampaging'
```
Transition actions can also be created using the `transitionTo` method of the `Ember.State` class. The
following example StateManagers are equivalent:
```javascript
aManager = Ember.StateManager.create({
stateOne: Ember.State.create({
changeToStateTwo: Ember.State.transitionTo('stateTwo')
}),
stateTwo: Ember.State.create({})
})
bManager = Ember.StateManager.create({
stateOne: Ember.State.create({
changeToStateTwo: function(manager, context){
manager.transitionTo('stateTwo', context)
}
}),
stateTwo: Ember.State.create({})
})
```
