processing_function()

void MayaFlux::Buffers::ChannelProcessor::processing_function ( std::shared_ptr< Buffer >  buffer )

overridevirtual

Processes a buffer by combining tributary buffers and node network output.

Parameters

buffer

Buffer to process (should be the root buffer)

This method implements a hierarchical data aggregation algorithm:

1. Processes all tributary buffers to ensure current data
2. Combines their outputs into the root buffer using a weighted averaging algorithm
3. Incorporates node network output if present

The combination algorithm can be customized in the implementation.

Implements MayaFlux::Buffers::BufferProcessor.
