FDataflowNode

FNode Base class for node based evaluation within the Dataflow graph.

API > API/Runtime > API/Runtime/DataflowCore

FNode Base class for node based evaluation within the Dataflow graph.

Note : Do NOT create mutable variables in the classes derived from FDataflowNode. The state is stored on the FContext. The Evaluate is const to allow support for multithreaded evaluation.
