on_attach()

template<GpuImageSource T>

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

inlineoverridevirtual

Validate the buffer type and reset executor state.

Throws std::invalid_argument if the buffer cannot be cast to T. Called automatically by BufferProcessingChain::add_processor.

Parameters

buffer

The Buffer to attach to.

Reimplemented from MayaFlux::Buffers::BufferProcessor.
