Class FunctionNImpl<R>

java.lang.Object
  info.javelot.functionalj.FunctionNImpl<R>

Type Parameters:

R - the type of the result returned by the function.

All Implemented Interfaces:

FunctionN<R>

Direct Known Subclasses:

StdReflectFunction

public abstract class FunctionNImpl<R>
extends Object
implements FunctionN<R>

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.
