		HdStResourceRegistry *	resourceRegistry,
		TfToken const &	role,
		HdBufferSpecVector const &	bufferSpecs,
		HdBufferArrayUsageHint	usageHint,

	)

Constructor.

virtual HDST_API ~_StripedInterleavedBuffer ( )

virtual

Destructor. It invalidates _rangeList.

Member Function Documentation

HDST_API HdStBufferResourceSharedPtr _AddResource	(	TfToken const &	name,
		HdTupleType	tupleType,
		int	offset,
		int	stride
	)

protected

Adds a new, named GPU resource and returns it.

virtual HDST_API void DebugDump ( std::ostream & out ) const

virtual

Debug output.

Implements HdBufferArray.

virtual HDST_API bool GarbageCollect ( )

virtual

perform compaction if necessary, returns true if it becomes empty.

Implements HdBufferArray.

HDST_API HdBufferSpecVector GetBufferSpecs ( ) const

Reconstructs the bufferspecs and returns it (for buffer splitting)

HDST_API HdStBufferResourceSharedPtr GetResource ( ) const

TODO: We need to distinguish between the primvar types here, we should tag each HdBufferSource and HdBufferResource with Constant, Uniform, Varying, Vertex, or FaceVarying and provide accessors for the specific buffer types.

Returns the GPU resource. If the buffer array contains more than one resource, this method raises a coding error.

HDST_API HdStBufferResourceSharedPtr GetResource ( TfToken const & name )

Returns the named GPU resource.

This method returns the first found resource. In HD_SAFE_MODE it checks all underlying GL buffers in _resourceMap and raises a coding error if there are more than one GL buffers exist.

HdStBufferResourceNamedList const& GetResources ( ) const

inline

Returns the list of all named GPU resources for this bufferArray.

Definition at line 280 of file interleavedMemoryManager.h.

int GetStride ( ) const

inline

Returns the stride.
