public interface ChainedFunctionI

Specifies functions than can be used in a chain. The apply(Evaluator, Node, Object) is called during evaluation by the ChainingOpPfmc when the function is on the right hand side of the composition operator.

This interface should not be used with UnaryFunction, BinaryFunction, NaryFunction, NaryBinaryFunction, or NullaryFunction.
