# UI Nodes
You may have seen the `omni.ui` extension that gives you the ability to create user interface elements through Python scripting. OmniGraph provides some nodes that can be used to do the same thing through an action graph.
These nodes provide an interface to the equivalent `omni.ui` script elements. The attributes of the nodes match the parameters you would pass to the script.
| Node | omni.ui Equivalent |
| --------------------------------------------------------------------------------------------------- | -------------------------------------------------------------- |
| {ref}`Button<GENERATED - Documentation _ognomni.graph.ui.Button>` | {py:class}`omni.ui.Button` |
| {ref}`ComboBox<GENERATED - Documentation _ognomni.graph.ui.ComboBox>` | {py:class}`omni.ui.ComboBox` |
| {ref}`OnWidgetClicked<GENERATED - Documentation _ognomni.graph.ui.OnWidgetClicked>` | {py:class}`omni.ui.Widget.call_mouse_pressed_fn` |
| {ref}`OnWidgetValueChanged<GENERATED - Documentation _ognomni.graph.ui.OnWidgetValueChanged>` | {py:class}`omni.ui.Widget.add_value_changed_fn` |
| {ref}`Slider<GENERATED - Documentation _ognomni.graph.ui.Slider>` | {py:class}`omni.ui.IntSlider` {py:class}`omni.ui.FloatSlider` |
| {ref}`VStack<GENERATED - Documentation _ognomni.graph.ui.VStack>` | {py:class}`omni.ui.VStack` |
## How To Use Them
The UI nodes are meant to be triggered to exist temporarily, meaning you want to ensure that they are part of a graph that creates them only once and then destroys them once their utility has ended.

# OmniGraph Action Graphs
## Introduction to Action Graphs
Provides visual-programming graphs to help designers bring their omniverse creations to life. Action Graphs are
triggered by events and can execute nodes which modify the stage.
## The Action Graph Extension
Contains nodes which work only with Action Graphs. Compute Nodes from other extensions can be used with Action Graphs;
for example omni.graph.nodes.

# Action Graph Overview
For a hands-on introduction to OmniGraph Action Graphs see
[Action Graph Quickstart](https://docs.omniverse.nvidia.com/prod_extensions/prod_extensions/ext_omnigraph/quickstart.html)
For more comprehensive and thorough documentation on various OmniGraph features see {ref}`ogn_user_guide`
Action Graphs are comprised of any number of separate chains of nodes, like deformer graphs. However there are important differences which make Action graphs more suited to particular applications.
## Event Sources
Action graphs are *event driven*, which means that each chain of nodes must start with an *Event Source* node. Each event source node can be thought of as an entry point of the graph.
*Event Source* nodes are named with an *On* prefix, never have an *execution* input attribute, and always have at least one output *execution* attribute.
| Event Source Nodes |
| ------------------------------------------------------------------------------------------ |
| {ref}`On Keyboard Input <GENERATED - Documentation _ognomni.graph.action.OnKeyboardInput>` |
| {ref}`On Tick <GENERATED - Documentation _ognomni.graph.action.OnTick>` |
| {ref}`On Playback Tick <GENERATED - Documentation _ognomni.graph.action.OnPlaybackTick>` |
| {ref}`On Impulse Event <GENERATED - Documentation _ognomni.graph.action.OnImpulseEvent>` |
| {ref}`On Object Change <GENERATED - Documentation _ognomni.graph.action.OnObjectChange>` |
| {ref}`On Custom Event <GENERATED - Documentation _ognomni.graph.action.OnCustomEvent>` |
## Execution Attributes
Action graphs make use of *execution*-type attributes.
The *execution* evaluator works by following *execution* connections downstream and computing nodes it encounters until there are no more downstream connections to follow. The entire chain is executed to completion. When there is no downstream node the execution terminates and the next node is popped off the *execution stack*
Note that if there is more than one downstream connection from an *execution* attribute, each path will be followed in an undetermined order. Multiple downstream chains can be executed in a fixed order either by chaining the end of one to the start of the other, or by using the {ref}`Sequence <GENERATED - Documentation _ognomni.graph.action.Sequence>` node.
The value of an *execution* attribute tells the evaluator what the next step should be in the chain. It can be one of:
| Value | Description
| ---------------- | ------------------------------------------------------------------------------------------- |
| DISABLED | Do not continue from this attribute. |
| ENABLED | Continue downstream from this attribute. |
| ENABLED_AND_PUSH | Save the current node on the *execution stack* and continue downstream from this attribute. |
| LATENT_PUSH | Save the current node as it performs some asynchronous operation |
| LATENT_FINISH | Finish the asynchronous operation and continue downstream from this attribute. |
# Flow Control
Many Action graphs will need to do different things depending on some state. In a python script you would use an *if* or *while* loop to accomplish this. Similarly in Action graph there are nodes which provide this branching functionality. Flow control nodes have more than one *execution* output attribute, which is used to branch the evaluation flow.
| Flow Control Nodes |
| --------------------------------------------------------------------------- |
| {ref}`Branch <GENERATED - Documentation _ognomni.graph.action.Branch>` |
| {ref}`ForEach <GENERATED - Documentation _ognomni.graph.action.ForEach>` |
| {ref}`For Loop <GENERATED - Documentation _ognomni.graph.action.ForLoop>` |
| {ref}`Flip Flop <GENERATED - Documentation _ognomni.graph.action.FlipFlop>` |
| {ref}`Gate <GENERATED - Documentation _ognomni.graph.action.Gate>` |
| {ref}`Sequence <GENERATED - Documentation _ognomni.graph.action.Sequence>` |
| {ref}`Delay <GENERATED - Documentation _ognomni.graph.action.Delay>` |

// The comments in this file are intended to be read top to bottom, like a book.
// This file defines flatcache::StageWithHistory, an instance of which stores
// the current stage and a configurable number of frames of state history. It
// is thread safe, in the sense that the current state can be safely read and
// written in parallel with multiple threads reading the history. The class
// definition is towards the end of this file. We first define some basic types,
// a read/write accessor class for use by the main/game/sim thread, and two
// read-only accessor classes for use on render threads. These classes provide
// access to an interpolated state and a window of state history respectively.
// To specify paths, attribute names, and attribute types we use
// flatcache::Path, flatcache::Token and graph::Type types, rather than
// USD's SdfPath, TfToken and TfType. This allows us to access the stage and
// history without including USD headers.
// The main class is this file is StageWithHistory, which is defined towards
// the end of the file.

// A hashmap implemented with the following decisions:
//
// * Memory is allocated in a single contiguous buffer so that find operations make linear cache line fetches as much
// as possible. This intends to make more easily predictable memory access patterns, and thus, easier hardware-level
// prefetch decisions. Similarly, whole-map iteration benefits from the same cache-friendly access patterns.
//
// * Find operations intentionally are coded without range checks on the main loop. This is a tradeoff of speed for
// less error-detection in release builds. To help mitigate this, debug builds do track probe counts to validate
// we don't exceed the possible length of the hashmap.
//
// * No opinion codified on thread synchronization. It can be used safely if done carefully, but this is not a
// guarantee of the implementation.
//
// * No iterators provided. If some batch operation must occur, use the forEach() function provided, which should
// suffice. The forEach() method should provide similar performance without the added risk of callers being able to
// arbitrarily cache iterators outside the control of the HashMap, its routines, or even its lifetime.
//
// * Deletes copy-constructor and copy-assignment for non-standard-layout mappings. This forces callers to implement
// these routines explicitly, favoring the clarity of reading intent in explicit implementation over ambiguity over
// compiler selection. Mappings that have standard-layout default to use a memcpy to copy data as fast as possible.
//
// * Implements allocateEntry() method, rather than insert()/emplace() methods mimicing std::unordered_map API. This
// does the minimum steps necessary to reserve address space for a key-value mapping, and provides the caller with
// the reserved buffer memory address for them to do their own construction, assignment, or initialization routines.
// This favors slightly more explicit coding patterns at the caller to force clarity of intent. In particular,
// it make more obvious the choice of the caller between construction vs assignment, and copy vs move semantics. It
// also offers greater flexibility without sacrificing performance.
//
// * ~HashMap() and clear() operate different depending on if KeyT and ValueT are known to be
// std::is_trivially_destructible. If they are, the fastest option is chosen: to deallocate the memory without
// iteration or explicitly destruction per-entry. Otherwise, the implementation iterates to non-trivially destruct
// each object in-place.

// has a guarantee on uniqueness, it does not necessarily lend to good distributions in a hash table. Two hash
// values that are multiples of each other will naturally colliide in any space-restricted hashmap.
// (Which, realistically, is all real hash maps since hardware memory is not infinite.) Applying a little salt on

* @enum PtrToPtrKind

* @details When getting an array-valued attribute for GPU access, you can
* optionally use this enum to ask for a GPU pointer to the GPU data
* pointer (eGpuPtrToGpuPtr), or a CPU pointer to the GPU data
* pointer (eCpuPtrToGpuPtr).
* The advantage of using eCpuPtrToGpuPtr is that you can dereference
* the returned pointer on the CPU, and pass the GPU data pointer as
* a CUDA kernel parameter.
* The advantage of using eGpuPtrToGpuPtr is that it makes it easier
* to extend kernels to operate on arrays of arrays later. Also it
* allows us to support allocation and resizing of array-valued
* attributes on the GPU in the future.
*
* PtrToPtrKind is not a parameter of methods returning arrays of
* arrays, for example getArrayGPU(). This is because there is no way
* to pass a variable length array of GPU pointers to a kernel using
* its CPU launch parameters. So GPU arrays of arrays always have to
* be passed to kernels as a GPU pointer to an array of GPU pointers.

* Carbonite registered strings.
*
* The Carbonite framework has a rich <a href="https://en.wikipedia.org/wiki/String_interning">string-interning</a>
* interface that is very easily used through the RString (and other) classes. This implements a <a
* href="https://en.wikipedia.org/wiki/Flyweight_pattern">Flyweight pattern</a> for strings. The registered string
* interface is fully @rstref{ABI-safe <abi-compatibility>} due to versioning, and can even be used in an application
* prior to the `main()`, `WinMain()` or `DllMain()` functions being called. Furthermore, the API is fully thread-safe.
*
* Registered strings have pre-computed hashes which make them ideal for identifiers and map keys, and string
* (in-)equality checks are O(1) constant time. For ordered containers, registered strings have an `owner_before()`
* function that can be used for stable (though not lexicographical) ordering. If lexicographical ordering is desired,
* O(n) `compare()` functions are provided.
*
* Variations exist around case-sensitivity. The RStringU class (the U stands for "un-cased" which is used in this API
* to denote case-insensitivity) is used to register a string that will compare in a case-insensitive manner. Although
* RString and RStringU cannot be directly compared for equality, RString::toUncased() exists to explicitly create a
* case-insensitive RStringU from an RString which can then be compared.
*
* Variations also exist around using registered strings as a key value. It can be useful to have an associated number
* to denote multiple instances of a registered string: hence the RStringKey and RStringUKey classes.
*
* To register a string, pass a string to the RString constructor RAII-style. Strings that are registered stay as such
* for the entire run of the application; strings are never unregistered. Registered strings are stored in a named
* section of shared memory accessible by all modules loaded by an application. The memory for registered strings is
* allocated directly from the operating system to avoid cross-DLL heap issues.
*
* @note Registered strings are a limited resource, but there exists slots for approximately two million strings.
*
* Variations:
* * RStringU - an "un-cased" (i.e. case-insensitive) registered string
* * RStringKey - Adds a numeric component to RString to create an identifier or key.
* * RStringUKey - Adds a numeric component to RStringU to create an identifier or key that is case-insensitive.

//! Internal function used by all other allocation functions.
//!
//! This function is the entry point into `carb.dll`/`libcarb.so` for @ref carb::allocate(), @ref carb::deallocate(),
//! and @ref carb::reallocate(). There are four modes to this function:
//! - If @p p is `nullptr` and @p size is `0`, no action is taken and `nullptr` is returned.
//! - If @p p is not `nullptr` and @p size is `0`, the given pointer is deallocated and `nullptr` is returned.
//! - If @p p is `nullptr` and @p size is non-zero, memory of the requested @p size and alignment specified by @p align
//! is allocated and returned. If an allocation error occurs, `nullptr` is returned.
//! - If @p p is not `nullptr` and @p size is non-zero, the memory is reallocated and copied (as if by `std::memcpy`) to
//! the new memory block, which is returned. If @p p can be resized in situ, the same @p p value is returned. If an
//! error occurs, `nullptr` is returned.
//!
//! @note Using this function requires explicitly linking with `carb.dll`/`libcarb.so` if @ref CARB_REQUIRE_LINKED is
//! `1`. Otherwise, the caller must ensure that `carb.dll`/`libcarb.so` is already loaded before calling this function.
//! Use in situations where the Carbonite Framework is already loaded (i.e. plugins) does not require explicitly linking
//! against Carbonite as this function will be found dynamically at runtime.
//!
//! @warning Do not call this function directly. Instead call @ref carb::allocate(), @ref carb::deallocate(), or
//! @ref carb::reallocate()
//!
//! @see carb::allocate() carb::reallocate() carb::deallocate()
//! @param p The pointer to re-allocate or free. May be `nullptr`. See explanation above.
//! @param size The requested size of the memory region in bytes. See explanation above.
//! @param align The requested alignment of the memory region in bytes. Must be a power of two. See explanation above.
//! @returns Allocated memory, or `nullptr` upon deallocation, or `nullptr` on allocation when an error occurs.

//! Defines the framework for creating Carbonite applications and plugins.
//!
//! See \carb_framework_overview for high-level documentation on core concepts, using @ref Framework, and creating
//! plugins.
//!
//! Plugins are shared libraries with a .plugin.dll/.so suffix. The plugins are named with the .plugin suffix to support
//! plugin discovery and support cohabitation with other supporting .dll/.so libraries in the same folder. It is a
//! recommended naming pattern, but not mandatory.
//!
//! Plugin library file format:
//!
//! - Windows: <plugin-name>.plugin.dll
//! - Linux: lib<plugin-name>.plugin.so
//!
//! A plugin implements one or many interfaces and has a name which uniquely identifies it to the framework. The
//! plugin's name usually matches the filename, but it is not mandatory, the actual plugin name is provided by the
//! plugin via @ref carb::OnPluginRegisterFn.
//!
//! "Static" plugin can also be registered with @ref Framework::registerPlugin() function, thus no shared library will
//! be involved.
//!
//! @ref Framework comes with 3 static plugins:
//!
//! - @ref carb::logging::ILogging
//! - @ref carb::filesystem::IFileSystem
//! - @ref carb::assert::IAssert
//!
//! These plugins are used by @ref Framework itself. Without @ref carb::logging::ILogging, @ref Framework won't be able
//! to log messages. Without @ref carb::filesystem::IFileSystem, @ref Framework won't be able to load any "dynamic"
//! plugins. Without @ref carb::assert::IAssert, assertion failures will simply write a message to stderr and abort.
//!
//! It's up to the application to register these needed plugins. @ref OMNI_CORE_INIT() performs this registration on
//! the user's behalf.
//!
//! The term "client" is often used across the @ref Framework API. Client is either:
//!
//! - A plugin. Here the client name is the same as the plugin name.
//!
//! - An application. The module which dynamically links with the Framework and uses @ref carb::acquireFramework().
//!
//! - Scripting bindings. This is technically similar to an application, in that it dynamically links with the @ref
//! Framework and uses @ref carb::acquireFramework().
//!
//! Clients are uniquely identified by their name. Many functions accept client name as an argument. This allows @ref
//! Framework to create a dependency tree of clients. This dependency tree allows the safe unloading of plugins.
//!
//! @thread_safety Unless otherwise noted, @ref Framework functions are thread-safe and may be called from multiple
//! threads simultaneously.

/**
* Macro that allows disabling pybind's use of RTTI to perform duck typing.
*
* Given a pointer, pybind uses RTTI to figure out the actual type of the pointer (e.g. given an `IObject*`, RTTI can be
* used to figure out the pointer is really an `IWindow*`). once pybind knows the "real" type, is generates a PyObject
* that contains wrappers for all of the "real" types methods.
*
* Unfortunately, RTTI is compiler dependent (not @rstref{ABI-safe <abi-compatibility>}) and we've disabled it in much
* of our code.
*
* The `polymorphic_type_hook` specializations generated by this macro disables pybind from using RTTI to find the
* "real" type of a pointer. this mean that when using our bindings in Python, you have to "cast" objects to access a
* given interface. For example:
* ```python
* obj = func_that_returns_iobject()
* win = IWindow(obj) # a cast. None is returned if the cast fails.
* if win:
* win->title = "hi"
* ```
*
* As an aside, since implementations can implement multiple interfaces and the actual implementations are hidden to
* pybind (we create bindings for interfaces not implementations), the pybind "duck" typing approach was never going to
* work for us. Said differently, some sort of "cast to this interface" was inevitable.
* @param TYPE The type to disable Pythonic dynamic casting for.

* Macros to declare a plugin implementation dependencies.
*
* If a plugin lists an interface "A" as dependency it is guaranteed that `carb::Framework::acquireInterface<A>()` call
* will return it, otherwise it can return `nullptr`. The Framework checks and resolves all dependencies before loading
* the plugin. If the dependency cannot be loaded (i.e. no plugin satisfies the interface, or a circular load is
* discovered) then the plugin will fail to load and `nullptr` will be returned from the
* carb::Framework::acquireInterface() function.
*
* @note Circular dependencies can exist as long as they are not stated in the CARB_PLUGIN_IMPL_DEPS() macros. For
* instance, assume plugins *Alpha*, *Beta*, and *Gamma*. *Alpha* is dependent on *Beta*; *Beta* is dependent on
* *Gamma*. *Gamma* is dependent on *Alpha*, but cannot list *Alpha* in its CARB_PLUGIN_IMPL_DEPS() macro, nor
* attempt to acquire and use it in *Gamma*'s carbOnPluginStartup() function. At a later point from within *Gamma*, the
* desired interface from *Alpha* may be acquired and used. However, in terms of unload order, *Alpha* will be unloaded
* first, followed by *Beta* and finally *Gamma*. In this case the *Gamma* carbOnPluginShutdown() function must account

* is injected to ensure the plugin can use these "common" plugins.
*
* This macro avoids taking dependencies on these "common" plugins. When calling this macro, only the "minimal" boiler
* plate code is generated in order for the plugin to work. It's up to the developer to add additional code to make the
* plugin compatible with any desired "common" plugin.
*
* Use of this macro is rare in Omniverse.
