process_sample()

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

overridevirtual

Processes a single sample through the chain.

Parameters

input

The input sample

Returns

The output after processing through both nodes

The input is first processed by the source node, and the result is then processed by the target node.

Implements MayaFlux::Nodes::Node.
