on_detach()

void MayaFlux::Buffers::TransferProcessor::on_detach ( std::shared_ptr< Buffer >  )

overridevirtual

Called when this processor is detached from a buffer.

Parameters

buffer

Buffer this processor is being detached from

Provides an opportunity for the processor to clean up buffer-specific state or release resources. With expanded processor capabilities, this method should also:

• Release Hardware Resources: Clean up GPU memory, CUDA contexts, or other acceleration resources
• Finalize Backend Operations: Ensure all pending backend operations are completed
• Reset Processing State: Clear any buffer-specific optimization parameters or cached data
• Restore Default Backend: Return to default processing backend if override was applied
• Synchronize Operations: Ensure all parallel processing operations have completed

Default implementation does nothing, but proper resource management in derived classes is crucial for optimal performance and preventing resource leaks.

Reimplemented from MayaFlux::Buffers::BufferProcessor.
