Interface class for representing range (subset) locator of HdBufferArray.
Each memory management strategy defines a specialized range class which is inherited of this interface so that client (drawItem) can be agnostic about the implementation detail of aggregation.
Definition at line 58 of file bufferArrayRangeGL.h.
|
virtual |
Destructor (do nothing). The specialized range class may want to do something for garbage collection in its destructor. However, be careful not do any substantial work here (obviously including any kind of GL calls), since the destructor gets called frequently on various contexts.
|
overridevirtual |
Sets the bufferSpecs for all resources.
Implements HdBufferArrayRange.
|
pure virtual |
Returns the GPU resource. If the buffer array contains more than one resource, this method raises a coding error.
Implemented in HdStVBOMemoryManager::_StripedBufferArrayRange, HdStVBOSimpleMemoryManager::_SimpleBufferArrayRange, and HdStInterleavedMemoryManager::_StripedInterleavedBufferRange.
|
pure virtual |
Returns the named GPU resource.
Implemented in HdStVBOMemoryManager::_StripedBufferArrayRange, HdStVBOSimpleMemoryManager::_SimpleBufferArrayRange, and HdStInterleavedMemoryManager::_StripedInterleavedBufferRange.
|
pure virtual |
Returns the list of all named GPU resources for this bufferArrayRange.
