on_attach()

void MayaFlux::Buffers::PresentProcessor::on_attach ( const std::shared_ptr< Buffer > &  buffer )

overridevirtual

Called when processor is attached to a buffer.

Parameters

buffer

Buffer being attached to

Validates that the buffer is a RootGraphicsBuffer and ensures token compatibility for graphics rendering.

Reimplemented from MayaFlux::Buffers::BufferProcessor.
