__init__(*args, **kwargs)

as_read_only(self: omni.graph.core._omni_graph_core.AttributeData) → omni.graph.core._omni_graph_core.AttributeData

Returns read-only variant of the attribute data.

Returns: Read-only variant of the attribute data.
Return type: AttributeData

copy_data(self: omni.graph.core._omni_graph_core.AttributeData, rhs: omni.graph.core._omni_graph_core.AttributeData) → bool

Copies the AttributeData data into this object’s data.

Parameters: rhs (omni.graph.core.AttributeData) – Attribute data to be copied - must be the same type as the current object to work
Returns: True if the data was successfully copied, else False.
Return type: bool

cpu_valid(self: omni.graph.core._omni_graph_core.AttributeData) → bool

Returns whether this attribute data object is currently valid on the cpu.

Returns: True if the data represented by this object currently has a valid value in CPU memory
Return type: bool

get(self: omni.graph.core._omni_graph_core.AttributeData, on_gpu: bool = False) → object

Gets the current value of the attribute data

Parameters: on_gpu (bool) – Is the data to be retrieved from the GPU?
Returns: Value of the attribute data
Return type: Any

get_array(self: omni.graph.core._omni_graph_core.AttributeData, on_gpu: bool = False, get_for_write: bool, reserved_element_count: int) → object

Gets the current value of the attribute data.

Parameters

on_gpu (bool) – Is the data to be retrieved from the GPU?
get_for_write (bool) – Should the data be retrieved for writing?
reserved_element_count (int) – If the data is to be retrieved for writing, preallocate this many elements

Returns

Value of the array attribute data

Return type

Any

get_extended_type(self: omni.graph.core._omni_graph_core.AttributeData) → omni.graph.core._omni_graph_core.ExtendedAttributeType

Returns the extended type of the current attribute data.

Returns: Extended type of the attribute data object
Return type: omni.graph.core.ExtendedAttributeType

get_name(self: omni.graph.core._omni_graph_core.AttributeData) → str

Returns the name of the current attribute data.

Returns: Name of the attribute data object
Return type: str

get_resolved_type(self: omni.graph.core._omni_graph_core.AttributeData) → omni.graph.core._omni_graph_core.Type

Returns the resolved type of the extended attribute data. Only valid for attributes with union/any extended types.

Returns: Resolved type of the attribute data object
Return type: omni.graph.core.Type

get_type(self: omni.graph.core._omni_graph_core.AttributeData) → omni.graph.core._omni_graph_core.Type

Returns the type of the current attribute data.

Returns: Type of the attribute data object
Return type: omni.graph.core.Type

gpu_valid(self: omni.graph.core._omni_graph_core.AttributeData) → bool

Returns whether this attribute data object is currently valid on the gpu.

Returns: True if the data represented by this object currently has a valid value in GPU memory
Return type: bool

is_read_only(self: omni.graph.core._omni_graph_core.AttributeData) → bool

Returns whether this attribute data object is read-only or not.

Returns: True if the data represented by this object is read-only
Return type: bool

is_valid(self: omni.graph.core._omni_graph_core.AttributeData) → bool

Returns whether this attribute data object is valid or not.

Returns: True if the data represented by this object is valid
Return type: bool

resize(self: omni.graph.core._omni_graph_core.AttributeData, element_count: int) → bool

Sets the number of elements in the array represented by this object.

Parameters: element_count (int) – Number of elements to reserve in the array
Returns: True if the array was resized, False if not (e.g. if the attribute data was not an array type)
Return type: bool

set(self: omni.graph.core._omni_graph_core.AttributeData, value: object, on_gpu: bool = False) → bool

Sets the value of the attribute data

Parameters

value (Any) – New value of the attribute data
on_gpu (bool) – Is the data to be set on the GPU?

Returns
