omniverse-code/kit/gsl/README.md | # GSL: Guidelines Support Library
[](https://travis-ci.org/Microsoft/GSL) [](https://ci.appveyor.com/project/neilmacintosh/GSL)
The Guidelines Support Library (GSL) contains functions and types that are suggested for use by the
[C++ Core Guidelines](https://github.com/isocpp/CppCoreGuidelines) maintained by the [Standard C++ Foundation](https://isocpp.org).
This repo contains Microsoft's implementation of GSL.
The library includes types like `span<T>`, `string_span`, `owner<>` and others.
The entire implementation is provided inline in the headers under the [gsl](./include/gsl) directory. The implementation generally assumes a platform that implements C++14 support.
While some types have been broken out into their own headers (e.g. [gsl/span](./include/gsl/span)),
it is simplest to just include [gsl/gsl](./include/gsl/gsl) and gain access to the entire library.
> NOTE: We encourage contributions that improve or refine any of the types in this library as well as ports to
other platforms. Please see [CONTRIBUTING.md](./CONTRIBUTING.md) for more information about contributing.
# Project Code of Conduct
This project has adopted the [Microsoft Open Source Code of Conduct](https://opensource.microsoft.com/codeofconduct/). For more information see the [Code of Conduct FAQ](https://opensource.microsoft.com/codeofconduct/faq/) or contact [[email protected]](mailto:[email protected]) with any additional questions or comments.
# Usage of Third Party Libraries
This project makes use of the [Google Test](https://github.com/google/googletest) testing library. Please see the [ThirdPartyNotices.txt](./ThirdPartyNotices.txt) file for details regarding the licensing of Google Test.
# Quick Start
## Supported Compilers
The GSL officially supports the current and previous major release of MSVC, GCC, Clang, and XCode's Apple-Clang.
See our latest test results for the most up-to-date list of supported configurations.
Compiler |Toolset Versions Currently Tested| Build Status
:------- |:--|------------:
XCode |11.4 & 10.3 | [](https://travis-ci.org/Microsoft/GSL)
GCC |9 & 8| [](https://travis-ci.org/Microsoft/GSL)
Clang |11 & 10| [](https://travis-ci.org/Microsoft/GSL)
Visual Studio with MSVC | VS2017 (15.9) & VS2019 (16.4) | [](https://ci.appveyor.com/project/neilmacintosh/GSL)
Visual Studio with LLVM | VS2017 (Clang 9) & VS2019 (Clang 10) | [](https://ci.appveyor.com/project/neilmacintosh/GSL)
Note: For `gsl::byte` to work correctly with Clang and GCC you might have to use the ` -fno-strict-aliasing` compiler option.
---
If you successfully port GSL to another platform, we would love to hear from you!
- Submit an issue specifying the platform and target.
- Consider contributing your changes by filing a pull request with any necessary changes.
- If at all possible, add a CI/CD step and add the button to the table below!
Target | CI/CD Status
:------- | -----------:
iOS | 
Android | 
Note: These CI/CD steps are run with each pull request, however failures in them are non-blocking.
## Building the tests
To build the tests, you will require the following:
* [CMake](http://cmake.org), version 3.1.3 (3.2.3 for AppleClang) or later to be installed and in your PATH.
These steps assume the source code of this repository has been cloned into a directory named `c:\GSL`.
1. Create a directory to contain the build outputs for a particular architecture (we name it c:\GSL\build-x86 in this example).
cd GSL
md build-x86
cd build-x86
2. Configure CMake to use the compiler of your choice (you can see a list by running `cmake --help`).
cmake -G "Visual Studio 15 2017" c:\GSL
3. Build the test suite (in this case, in the Debug configuration, Release is another good choice).
cmake --build . --config Debug
4. Run the test suite.
ctest -C Debug
All tests should pass - indicating your platform is fully supported and you are ready to use the GSL types!
## Building GSL - Using vcpkg
You can download and install GSL using the [vcpkg](https://github.com/Microsoft/vcpkg) dependency manager:
git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
vcpkg install ms-gsl
The GSL port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
## Using the libraries
As the types are entirely implemented inline in headers, there are no linking requirements.
You can copy the [gsl](./include/gsl) directory into your source tree so it is available
to your compiler, then include the appropriate headers in your program.
Alternatively set your compiler's *include path* flag to point to the GSL development folder (`c:\GSL\include` in the example above) or installation folder (after running the install). Eg.
MSVC++
/I c:\GSL\include
GCC/clang
-I$HOME/dev/GSL/include
Include the library using:
#include <gsl/gsl>
## Usage in CMake
The library provides a Config file for CMake, once installed it can be found via
find_package(Microsoft.GSL CONFIG)
Which, when successful, will add library target called `Microsoft.GSL::GSL` which you can use via the usual
`target_link_libraries` mechanism.
## Debugging visualization support
For Visual Studio users, the file [GSL.natvis](./GSL.natvis) in the root directory of the repository can be added to your project if you would like more helpful visualization of GSL types in the Visual Studio debugger than would be offered by default.

Interface for monitoring and handling changes in bundles and attributes.
The IBundleChanges_abi is an interface that provides methods for checking whether bundles and attributes
have been modified, and cleaning them if they have been modified. This is particularly useful in scenarios
where it's crucial to track changes and maintain the state of bundles and attributes.
This interface provides several methods for checking and cleaning modifications, each catering to different
use cases such as handling single bundles, multiple bundles, attributes, or specific attributes of a single bundle.
The methods of this interface return a BundleChangeType enumeration that indicates whether the checked entity
(bundle or attribute) has been modified.

Resolves attribute types given a set of attributes, that can have differing tuple counts and/or array depth,
and differing but convertible base data type.
The three input buffers are tied together, holding the attribute, the tuple
count, and the array depth of the types to be coupled.
This function will solve base type conversion by targeting the first provided type in the list,
for all other ones that require it.
For example if node 'makeTuple2' has two input attributes 'a' and 'b' and one output 'c' and we want to resolve
any float connection to the types 'a':float, 'b':float, 'c':float[2] (convertible base types and different tuple counts)
then the input buffers would contain:
attrsBuf = [a, b, c]
tuplesBuf = [1, 1, 2]
arrayDepthsBuf = [0, 0, 0]
rolesBuf = [AttributeRole::eNone, AttributeRole::eNone, AttributeRole::eNone]
This is worth noting that 'b' could be of any type convertible to float. But since the first provided
attribute is 'a', the type of 'a' will be used to propagate the type resolution.
Note that input attribute types are never inferred from output attribute types.
This function should only be called from the INodeType function 'on_connection_type_resolve'
Args:
attributesArray (list[omni.graph.core.Attribute]): Array of attributes to be resolved as a coupled group
tuplesArray (list[int]): Array of tuple count desired for each corresponding attribute. Any value
of None indicates the found tuple count is to be used when resolving.
arraySizesArray (list[int]): Array of array depth desired for each corresponding attribute. Any value
of None indicates the found array depth is to be used when resolving.
rolesArray (list[omni.graph.core.AttributeRole]): Array of role desired for each corresponding attribute. Any

Provides functions for creating nodes, making and breaking connections, and setting values.
Graph manipulation functions are undoable, value changes are not.
Functions are set up to be as flexible as possible, accepting a wide variety of argument variations.
Here is a summary of the interface methods you can access through this class, grouped by interface class. The ones
marked with an "*" indicate that they have both a classmethod version and an object method version. In those cases
the methods use object member values which have corresponding arguments in the classmethod version. (e.g. if the
method uses the "update_usd" member value then the method will also have a "update_usd:bool" argument)
Controller
\* edit Perform a collection of edits on a graph (the union of all interfaces)
async evaluate Runs evaluation on one or more graphs as a waitable (typically called from async tests)
evaluate_sync Runs evaluation on one or more graphs immediately
ObjectLookup

attribute_path Looks up an attribute string path from a description
attribute_type Looks up an og.Type from a description
graph Looks up an og.Graph from a description
node Looks up an og.Node from a description
node_path Looks up a node string path from a description
prim Looks up an Usd.Prim from a description
prim_path Looks up a Usd.Prim string path from a description
split_graph_from_node_path Separate a graph and a relative node path from a full node path
GraphController
\* connect Makes connections between attribute pairs
\* create_graph Creates a new og.Graph
\* create_node Creates a new og.Node
\* create_prim Creates a new Usd.Prim
\* create_variable Creates a new og.IVariable
\* delete_node Deletes a list of og.Nodes
\* disconnect Breaks connections between attribute pairs
\* disconnect_all Breaks all connections to and from specific attributes
\* expose_prim Expose a USD prim to OmniGraph through an importing node
NodeController
\* create_attribute Create a new dynamic attribute on a node
\* remove_attribute Remove an existing dynamic attribute from a node

"""Edit and/or create an OmniGraph from the given description.
This function provides a single call that will make a set of modifications to an OmniGraph. It can be used to
create a new graph from scratch or to make changes to an existing graph.
If the "undoable" mode is not set to False then a single undo will revert everything done via this call.
The description below contains different sections that perform different operations on the graph. They are
always done in the order listed to minimize conflicts. If you need to execute them in a different order then use
multiple calls to edit().
This function can be called either from the class or using an instantiated object. When callling from an object
context the arguments passed in will take precedence over the arguments provided to the constructor. Here are
some of the legal ways to call the edit function:
.. code-block:: python
# For example purposes "cmds()" is a function that returns a dictionary of editing commands
(graph, _, _, _) = og.Controller.edit("/TestGraph", cmds())
new_controller = og.Controller(graph)
new_controller.edit(cmds())
og.Controller.edit(graph, cmds())
new_controller.edit(graph, cmds())
new_controller.edit(graph, cmds(), undoable=False) # Overrides the normal undoable state of new_controller
Below is the list of the allowed operations, in the order in which they will be performed.
The parameters are described as lists, though if you have only one parameter for a given operation you can pass
it without it being in a list.
.. code-block:: python
{ OPERATION: [List, Of, Arguments] }
{ OPERATION: SingleArgument }
For brevity the shortcut "keys = og.Controller.Keys" is assumed to exist.
- keys.DELETE_NODES: NodeSpecs_t
Deletes a node or list of nodes. If the node specification is a relative path then it must be in the
list of full paths that the controller created in a previous call to edit().
{ keys.DELETE_NODES: ["NodeInGraph", "/Some/Other/Graph/Node", my_omnigraph_node] }
- keys.CREATE_NODES: [(Path_t, NodeType_t)]
Constructs a node of the given type at the given path. If the path is a relative one then it is
added directly under the graph being edited. A map is remembered between the given path, relative or
absolute, and the node created at it so that further editing functions can refer to the node by that
name directly rather than trying to infer the final full name.
{ keys.CREATE_NODES: [("NodeInGraph", "omni.graph.tutorial.SimpleData"),
("Inner/Node/Path", og.NodeType(node_type_name))] }
- keys.CREATE_PRIMS: [(Path_t, {ATTR_NAME: (AttributeType_t, ATTR_VALUE)}, Optional(PRIM_TYPE))]
Constructs a prim at path "PRIM_PATH" containing a set of attributes with specified types and values.
Only those attribute types supported by USD can be used here, though the type specification can be in
OGN form - invalid types result in an error. Whereas relative paths on nodes are treated as being
relative to the graph, for prims a relative path is relative to the stage root. Prims are not allowed
inside an OmniGraph and attempts to create one there will result in an error.
Note that the PRIM_TYPE can appear with or without an attribute definition. (Many prim types are part
of a schema and do not require explicit attributes to be added.)
{ keys.PRIMS: [("/World/Prim", {"speed": ("double", 1.0)}),
("/World/Cube", "Cube"),
("RootPrim", {
"mass": (Type(BaseDataType.DOUBLE), 3.0),
"force:gravity": ("double", 32.0)
})]}
- keys.CONNECT: [(AttributeSpec_t, AttributeSpec_t)]
Makes a connection between the given source and destination attributes. The local name of a newly
created node may be made as part of the node in the spec, or the node portion of the attribute path:
{ keys.CONNECT: [("NodeInGraph.outputs:value", ("inputs:value", "NodeInGraph"))]}
- keys.DISCONNECT: [(AttributeSpec_t, AttributeSpec_t)]
Breaks a connection between the given source and destination attributes. The local name of a newly
created node may be made as part of the node in the spec, or the node portion of the attribute path:
{ keys.DISCONNECT: [("NodeInGraph.outputs:value", ("inputs:value", "NodeInGraph"))]}
- keys.EXPOSE_PRIMS: [(cls.PrimExposureType, Prim_t, NewNode_t)]
Exposes a prim to OmniGraph through creation of one of the node types designed to do that.
The first member of the tuple is the method used to expose the prim. The prim path is
the second member of the tuple and it must already exist in the USD stage. The third member
of the tuple is a node name with the same restrictions as the name in the CREATE_NODES edit.
{ keys.EXPOSE_PRIMS: [(cls.PrimExposureType.AS_BUNDLE, "/World/Cube", "BundledCube")] }
- keys.SET_VALUES: [AttributeSpec_t, Any] or [AttributeSpec_t, Any, AttributeType_t]
Sets the value of the given list of attributes.
{ keys.SET_VALUES[("/World/Graph/Node.inputs:attr1", 1.0), (("inputs:attr2", node), 2.0)] }
In the case of extended attribute types you may also need to supply a data type, which is the type the
attribute will resolve to when the value is set. To supply a type, add it as a third parameter to the
attribute value:
{ keys.SET_VALUES[("inputs:ext1", node), 2.0, "float"] }
- keys.CREATE_VARIABLES: [(VariableName_t, VariableType_t)]
Constructs a variable on the graph with the given name and type. The type can be specified
as either a ogn type string (e.g. "float4"), or as an og.Type (e.g. og.Type(og.BaseDataType.FLOAT))
{ keys.CREATE_VARIABLES[("velocity", "float3"), ("count", og.Type(og.BaseDataType.INT))] }
Here's a simple call that first deletes an existing node "/World/PushGraph/OldNode", then creates two nodes of
type "omni.graph.tutorials.SimpleData", connects their "a_int" attributes, disconnects their "a_float"
attributes and sets the input "a_int" of the source node to the value 5. It also creates two unused USD Prim
nodes, one with a float attribute named "attrFloat" with value 2.0, and the other with a boolean attribute
named "attrBool" with the value true.
.. code-block:: python
controller = og.Controller()
keys = og.Controller.Keys
(graph, nodes_constructed, prims_constructed, path_to_object_map) = controller.edit("/World/PushGraph", {
keys.DELETIONS: [
"OldNode"
],
keys.CREATE_NODES: [
("src", "omni.graph.tutorials.SimpleData"),
("dst", "omni.graph.tutorials.SimpleData")
],
keys.CREATE_PRIMS: [
("Prim1", {"attrFloat": ("float", 2.0)),
("Prim2", {"attrBool": ("bool", true)),
],
keys.CONNECT: [
("src.outputs:a_int", "dst.inputs:a_int")
],
keys.DISCONNECT: [
("src.outputs:a_float", "dst.inputs:a_float")
],
keys.SET_VALUES: [
("src.inputs:a_int", 5)
]
keys.CREATE_VARIABLES: [
("a_float_var", og.Type(og.BaseDataType.FLOAT)),
("a_bool_var", "bool")
]
}
)
.. note::
The controller object remembers where nodes are created so that you can use short forms for the node paths
for convenience. That's why in the above graph the node paths for creation and the node specifications in
the connections just says "src" and "dst". As they have no leading "/" they are treated as being relative
to the graph path and will actually end up in "/World/PushGraph/src" and "/World/PushGraph/dst".
Node specifications with a leading "/" are assumed to be absolute paths and must be inside the path of an
existing or created graph. e.g. the NODES reference could have been "/World/PushGraph/src", however using
"/src" would have been an error.
This node path mapping is remembered across multiple calls to edit() so you can always use the shortform
so long as you use the same Controller object.
Args:
obj: Either cls or self depending on how edit() was called
graph_id: Identifier that says which graph is being edited. See :py:meth:`GraphController.create_graph`
for the data types accepted for the graph description.
edit_commands: Dictionary of commands and parameters indicating what modifications are to be made
to the specified graph. A strict set of keys is accepted. Each of the values in the
dictionary can be either a single value or a list of values of the proscribed type.
path_to_object_map: Dictionary of relative paths mapped on to their full path after creation so that the
edit_commands can use either full paths or short-forms to specify the nodes.
update_usd: If specified then override whether to update the USD after the operations (default False)
undoable: If True the operation is added to the undo queue, else it is done immediately and forgotten
(default True)
Returns:
A 4-tuple consisting of:
- the og.Graph being used for the operation
- the list of og.Nodes created by the operation
- the list of Usd.Prims created by the operation
- the map of node/prim path name to the created og.Node/Usd.Prim objects. Can usually be ignored; it
will be used internally to manage the shortform names of the paths used in multiple commands.
Raises:
og.OmniGraphError if any of the graph creation instructions could not be fulfilled
The graph will be left in the partially constructed state it reached at the time of the error

One of these objects is created per-node, per-port, to contain getter and setter properties on dynamic

members are updated based on the addition and removal of dynamic attributes from their node. The base class
implementation for the attribute accessors, DynamicAttributeAccess, uses this to determine whether an attribute
access request was made on a static or dynamic attribute.
The per-node data on the database will contain one of these objects per port-type. When the database is
created it will be attached to the primary attribute access classes via the base class below,
DynamicAttributeAccess.

the base class of the attribute information can access it.

of pending elements to allocate for their array data (required since Fabric takes the element
counter as an argument to the data retrieval so it can't be set ahead of time). It is set when
a size is set, reset when a value is set, and read from Fabric when it's value is requested.
The key values will be the special attribute name that has "_size" appended to it (until such
time as the attribute value can support size access itself).

Each of the port containers, db.inputs/db.outputs/db.state, houses the attribute data access properties.
These containers are constructed when the database is created, with hardcoded properties for all statically
defined attributes. This class intercepts getattr/setattr/delattr calls to check to see if the property
being requested is a dynamic attribute, and if so then it uses the properties stored in the per-node data
as the access points.
So the lookup sequence goes:
db -> og.Database
.inputs -> ValuesForInput(DynamicAttributeAccess)
.myAttribute -> DynamicAttributeAccess.__getattr__
-> ValuesForInput.__getattr__ (if the above fails)
It makes the bold assumption that the attributes are all set up nicely; no duplicate names, invalid types,
missing configuration, etc.
Attributes use leading underscores to minimize name collisions with the dynamically added attributes. (Double
underscores would have been preferable but would have made access from the derived classes problematic.)

omniverse-code/kit/exts/omni.graph/omni/graph/core/_impl/data_typing.py | """Contains support for wrapping Python objects around FlatCache typed data
These patterns draw heavily on the interfaces used by numpy as that is what is provided when dealing with Python
data on the CPU. The intent is to make the data interface pattern as similar as possible to make dealing with it
more consistent, though not to try to replicate any of the numpy functionality - that is left up to the interpreter
of this data.
The data wrapper consists of a raw memory pointer and a set of type identification information that corresponds to the
types supported by FlatCache (including those that will be supported in the foreseeable future).
One major way that the data typing differs from numpy is in the shape specification. While numpy insists that its
data be a matrix (i.e. a shape of (2,3) means a fully populated 2x3 matrix) this shape specification can include
different index counts in each level to accommodate gathered data.
To avoid ambiguity the gathered element sizes are placed in a tuple, even when it's only a single value.
e.g. 4x4 matrix = shape(4, 4)
Array of 5 4x4 matrixes = shape(5, 4, 4)
Two gathered 4x4 matrixes = shape((2,), 4, 4)
Two gathered arrays of 5 and 6 4x4 matrixes = shape((5, 6), 4, 4)
Here's how the shapes correspond to the access patterns, where the values returned are either memory pointers to a
particular element or another DataWrapper which access the sub-array. The indexes in the shape are from largest
scope to smallest scope, so gathered size is first, then array size, then tuple size.
The index operator can be specified by one or more index values, traversing down multiple levels of the array hierarchy.
These two are equivalent, though the first is more efficient - wrapper[I, J, K], wrapper[I][J][K]
These are the shape types currently supported by FlatCache, using float values as examples:
None - "Item is a single value, not an array"
(2,) - "An array of two elements"
float[] of size 2
index[I] is the Ith element of the array
float[2]
index[I] is the Ith tuple member
((2,)) - "A gathered set of two items"
float with 2 gathered items
index[I] is the Ith gathered item
(2,3) - "An array of 2 arrays with 3 elements each"
float[3][] of size 2
item[I] = Ith float[3] in the array
item[I, J] = Jth tuple member of the Ith float[3] in the array
((2,),3) - "An array of two arrays with 3 elements each"
float[3] with 2 gathered items
item[I] = Ith gathered float[3]
item[I, J] = Jth tuple member of the Ith gathered float[3]
((3,4)) - "An array of 2 arrays, the first with 3 elements, the second with 4"
float[] with gathered items of sizes 3 and 4
item[I] = Ith gathered array of floats
item[I, J] = Jth element of the Ith gathered float[]
((2,3),3) - "An array of 2 arrays of arrays with 3 elements, the first is an array of 2 arrays, the second is an
array of 3 arrays"
float[3][] with 2 gathered array items of length 2 and 3 respectively
item[I] = Ith gathered array of float[3]s
item[I, J] = Jth element of the Ith gathered array of float[3]s
item[I, J, K] = Kth tuple member of the Jth element of the Ith gathered array of float[3]s
There are also special cases for arrays, which are like tuples but have two index numbers for row and column. The matrix
types can only have 2, 3, or 4 as their tuple count, and must have a base data type of double.
(2,2) - "A 2x2 matrix"
matrixd[2]
item[I] = Ith row of the matrix
item[I, J] = Jth column of the Ith row of the matrix
(3,2,2) - "An array of 2x2 matrixes"
array of matrixd[2] with 3 gathered items
item[I] = Ith matrix array element
item[I, J] = Jth row of the Ith matrix array element
item[I, J, K] = Kth column of the Jth row of the Ith matrix array element
((3),2,2) - "An array of 2x2 matrixes"
gathered matrixd[2] with 3 gathered items
item[I] = Ith gathered matrix
item[I, J] = Jth row of the Ith gathered matrix
item[I, J, K] = Kth column of the Jth row of the Ith gathered matrix
((2,3),2,2) - "An array of 2 arrays of 2x2 matrixes, the first with 2 elements, the second with 3 elements"
gathered matrixd[2][] with 2 gathered items consisting of an array of 2 matrixes and an array of
3 matrixes respectively
item[I] = Ith gathered matrix array
item[I, J] = Jth element of the Ith gathered matrix array
item[I, J, K] = Kth row of the Jth element of the Ith gathered matrix array
item[I, J, K, L] = Lth column of the Kth row of the Jth element of the Ith gathered matrix array
Note that while gathered arrays and regular arrays have the same access pattern they are conceptually different in that
a gathered array represents data from N different objects which a regular array represents N different values on the
same object.

"""
# A bundle can be described as an opaque collection of attributes that travel together through the graph, whose
# contents and types can be introspected in order to determine how to deal with them. This section describes how
# the typical node will interface with the bundle content access. Use of the attributes within the bundles is the
# same as for the extended type attributes, described with their access methods.
#
# An important note regarding GPU bundles is that the bundle itself always lives on the CPU, specifying a memory
# space of "GPU/CUDA" for the bundle actually means that the default location of the attributes it contains will
# be on the GPU.
#
# The main bundle is extracted the same as any other attribute, by referencing its generated database location.
# For this example the bundle will be called "color" and it will have members that could either be the set
# ("r", "g", "b", "a") or the set ("c", "m", "y", "k") with the obvious implications of implied color space.
# As with other attribute types the bundle attribute functions are available through an accessor
color_bundle = db.inputs.color
# The accessor can determine if it points to valid data through a property
valid_color = color_bundle.valid
# If you want to call the underlying Bundle ABI directly you can access the og.Bundle object
bundle_object = color_bundle.bundle
# It can be queried for the number of attributes it holds
bundle_attribute_count = color_bundle.size
# It can have its contents iterated over, where each element in the iteration is an accessor of the bundled attribute
for (bundled_attribute in color_bundle.attributes)
pass
# It can be queried for an attribute in it with a specific name
bundled_attribute = color_bundle.attribute_by_name(db.tokens.red)
# You can get naming information to identify where the bundle is stored you can also get a path
bundle_path = color_bundle.path
# *** The rest of these methods are for output bundles only, as they change the makeup of the bundle
# It can have its contents (i.e. attribute membership) cleared
computed_color_bundle.clear()
# It can be assigned to an output bundle, which merely transfers ownership of the bundle.
# The property setter for the bundle member is the mechanism for this.
color_bundle.bundle = some_other_bundle
# This is accomplished with the insert utility function, which can insert a number of different types of objects
# into a bundle. (The type of data it is passed determines what will be inserted.)
#
# The above function uses this variation, which inserts the bundle members into an existing bundle
computed_color_bundle.insert(color_bundle)
# It can have a single attribute from another bundle inserted into its current list, like if you don't want
# the transparency value in your output color
computed_color_bundle.clear()

# It can also add a brand new attribute with a specific type and name as a 2-tuple
og.Type FLOAT_TYPE(og.BaseDataType.FLOAT)

# *** When attributes are extracted from a bundle they will also be enclosed in a wrapper class og.RuntimeAttribute
# The wrapper class has access to the attribute description information, specifically the name and type
