process_sample()

double MayaFlux::Nodes::ChainNode::process_sample ( double  input = 0. )

overridevirtual

Processes a single data sample.

Parameters

input

The input sample value

Returns

The processed output sample value

This is the core processing method that all nodes must implement. It takes a single input value, applies the node's transformation algorithm, and returns the resulting output value.

For generator nodes that don't require input (like oscillators or stochastic generators), the input parameter may be ignored. Note: This method does NOT mark the node as processed. That responsibility belongs to the caller, typically a chained parent node or the root node.

Implements MayaFlux::Nodes::Node.
