Constructor.

virtual HDST_API HdStInterleavedMemoryManager::_StripedInterleavedBuffer::~_StripedInterleavedBuffer ( )

virtual

Destructor. It invalidates _rangeList.

		HdTupleType	tupleType,
		int	offset,
		int	stride
	)

protected

Adds a new, named GPU resource and returns it.

HDST_API void HdStInterleavedMemoryManager::_StripedInterleavedBuffer::_DeallocateResources ( )

protected

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

virtual

Debug output.

Implements HdBufferArray.

virtual HDST_API bool HdStInterleavedMemoryManager::_StripedInterleavedBuffer::GarbageCollect ( )

virtual

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

Implements HdBufferArray.

HDST_API HdBufferSpecVector HdStInterleavedMemoryManager::_StripedInterleavedBuffer::GetBufferSpecs ( ) const

Reconstructs the bufferspecs and returns it (for buffer splitting)

size_t HdStInterleavedMemoryManager::_StripedInterleavedBuffer::GetElementStride ( ) const

inline

Definition at line 238 of file interleavedMemoryManager.h.

HdStInterleavedMemoryManager* HdStInterleavedMemoryManager::_StripedInterleavedBuffer::GetManager ( ) const

inline

Definition at line 262 of file interleavedMemoryManager.h.

HDST_API HdStBufferResourceSharedPtr HdStInterleavedMemoryManager::_StripedInterleavedBuffer::GetResource ( ) const

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

HDST_API HdStBufferResourceSharedPtr HdStInterleavedMemoryManager::_StripedInterleavedBuffer::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& HdStInterleavedMemoryManager::_StripedInterleavedBuffer::GetResources ( ) const

inline

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

Definition at line 255 of file interleavedMemoryManager.h.

size_t HdStInterleavedMemoryManager::_StripedInterleavedBuffer::GetStride ( ) const

inline

Returns the stride.

Definition at line 234 of file interleavedMemoryManager.h.

virtual HDST_API void HdStInterleavedMemoryManager::_StripedInterleavedBuffer::Reallocate	(	std::vector< HdBufferArrayRangeSharedPtr > const &	ranges,
		HdBufferArraySharedPtr const &	curRangeOwner
	)

virtual

Performs reallocation. GLX context has to be set when calling this function.

Implements HdBufferArray.

void HdStInterleavedMemoryManager::_StripedInterleavedBuffer::SetNeedsCompaction ( )

inline

Mark to perform compaction on GarbageCollect()

Definition at line 229 of file interleavedMemoryManager.h.

void HdStInterleavedMemoryManager::_StripedInterleavedBuffer::SetNeedsReallocation ( )

inline

Mark to perform reallocation on Reallocate()
