on_attach()

void MayaFlux::Buffers::FeedbackProcessor::on_attach ( std::shared_ptr< Buffer >  buffer )

overridevirtual

Called when this processor is attached to a buffer.

Parameters

buffer

Buffer this processor is being attached to

Initializes the previous state storage to match the size of the attached buffer. If the buffer is a FeedbackBuffer, the processor will use its internal previous state.

Reimplemented from MayaFlux::Buffers::BufferProcessor.
