class IVertexAttribute;

The IVertexAttribute interface is the common interface implemented by all vertex attribute types. Applications normally create VertexAttribute, RawVertexAttribute, or ReadOnlyVertexAttribute objects and pass them to buffer and renderable node APIs through this interface.

A vertex attribute describes a stream of per-vertex or per-instance data, including scalar type, vector element count, entry count, usage hints, and data persistence behaviour. The attribute must be bound to an IVertexBuffer before it can be used for drawing.

Type methods

	Name	Description
	GetDataType	Returns the data type of a single scalar entry.
	GetVertexCount	Returns the number of vertices accessible through the attribute.
	GetAttributeElementCount	Returns the number of scalar elements in each attribute entry.
	GetDataTypeByteSize	Returns the byte size of a single scalar entry.

Usage methods

	Name	Description
	GetPerformanceHintCpu	Returns the CPU performance hint configured for the attribute.
	GetPerformanceHintGpu	Returns the GPU performance hint configured for the attribute.
	GetDataPersistenceFlags	Returns the data persistence flags configured for the attribute.

Binding methods

	Name	Description
	IsBoundToBuffer	Reports whether this attribute has already been bound to a buffer.
	BuildReadOnlyAttribute	Attempts to populate a read-only vertex attribute from this attribute.
