Class GeneralFunction

java.lang.Object

math.function.AbstractFunction

math.function.GeneralFunction

All Implemented Interfaces:

Function

public class GeneralFunction
extends AbstractFunction

A thin wrapper for a Function. Pass a lambda expression representing the function to the constructor to quickly obtain a concrete AbstractFunction instead of writing a new class that extends AbstractFunction.
