  info.javelot.functionalj.FunctionNImpl

All Implemented Interfaces:

FunctionN

Direct Known Subclasses:

StdReflectFunction

public abstract class FunctionNImpl

extends Object

implements FunctionN

A base implementation of the FunctionN interface, which implements all methods except for the FunctionN.call(Object[]) method - that is left to subclasses to implement in order to define a function of N parameters.
