BufferDescriptor Class Reference

#include "steam/engine/buffhandle.hpp"

Description

An opaque descriptor to identify the type and further properties of a data buffer.

For each kind of buffer, there is somewhere a BufferProvider responsible for the actual storage management. This provider may "lock" a buffer for actual use, returning a BuffHandle.

Note

this descriptor and especially the #subClassification_ is really owned by the BufferProvider, which may use (and even change) the opaque contents to organise the internal buffer management.
