Member Function Documentation

◆ allocateBuffer()

virtual BuffHandle allocateBuffer ( const lumiera::StreamType * )

inlinevirtual

allocate a new writable buffer with type and size according to the BuffDescr.

The actual provider of this buffer depends on the StateClosure implementation; it could be a temporary, located in the cache, used for feeding calculated frames over a network, etc.

Returns: a BuffHandle encapsulating the information necessary to get at the actual buffer address and for releasing the buffer.

Implements StateClosure_OBSOLETE.
