Constructor & Destructor Documentation

HDST_API HdStVBOSimpleMemoryManager::_SimpleBufferArray::_SimpleBufferArray	(	HdStResourceRegistry *	resourceRegistry,
		TfToken const &	role,
		HdBufferSpecVector const &	bufferSpecs,
		HdBufferArrayUsageHint	usageHint
	)

Constructor.

HDST_API HdStVBOSimpleMemoryManager::_SimpleBufferArray::~_SimpleBufferArray ( )

override

Destructor. It invalidates _range.

Member Function Documentation

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

protected

Adds a new, named GPU resource and returns it.

HDST_API void HdStVBOSimpleMemoryManager::_SimpleBufferArray::_DeallocateResources ( )

protected

HDST_API void HdStVBOSimpleMemoryManager::_SimpleBufferArray::DebugDump ( std::ostream & out ) const

overridevirtual

Debug output.

Implements HdBufferArray.

HDST_API bool HdStVBOSimpleMemoryManager::_SimpleBufferArray::GarbageCollect ( )

overridevirtual

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

Implements HdBufferArray.

HDST_API HdBufferSpecVector HdStVBOSimpleMemoryManager::_SimpleBufferArray::GetBufferSpecs ( ) const

Reconstructs the bufferspecs and returns it (for buffer splitting)

int HdStVBOSimpleMemoryManager::_SimpleBufferArray::GetCapacity ( ) const

inline

Returns current capacity. It could be different from numElements.

Definition at line 260 of file vboSimpleMemoryManager.h.

HDST_API size_t HdStVBOSimpleMemoryManager::_SimpleBufferArray::GetMaxNumElements ( ) const

overridevirtual

Returns the maximum number of elements capacity.

Reimplemented from HdBufferArray.

HDST_API HdStBufferResourceSharedPtr HdStVBOSimpleMemoryManager::_SimpleBufferArray::GetResource ( ) const

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

HDST_API HdStBufferResourceSharedPtr HdStVBOSimpleMemoryManager::_SimpleBufferArray::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& HdStVBOSimpleMemoryManager::_SimpleBufferArray::GetResources ( ) const

inline

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

Definition at line 277 of file vboSimpleMemoryManager.h.

HDST_API void HdStVBOSimpleMemoryManager::_SimpleBufferArray::Reallocate	(	std::vector< HdBufferArrayRangeSharedPtr > const &	ranges,
		HdBufferArraySharedPtr const &	curRangeOwner
	)

overridevirtual

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

Implements HdBufferArray.

HDST_API bool HdStVBOSimpleMemoryManager::_SimpleBufferArray::Resize ( int numElements )

Set to resize buffers. Actual reallocation happens on Reallocate()
