clear()

void MayaFlux::Buffers::VKBuffer::clear ( )

overridevirtual

Clear buffer contents.

If the buffer is host-visible and mapped the memory is zeroed. For device-local buffers the backend must provide a ClearBufferProcessor that performs the appropriate GPU-side clear.

Implements MayaFlux::Buffers::Buffer.
