java.lang.Object

Progeneric.Ptl.Functors.Compose2<T,TResult,TResult1,TResult2>

Type Parameters:

T - The type of the parameter of the method that this function object encapsulates.

TResult - The type of the return value of the method that this function object encapsulates.

TResult1 - The type of the return value of the method that the g1 function object encapsulates.

TResult2 - The type of the return value of the method that the g2 function object encapsulates.

All Implemented Interfaces:

IFunc1Arg<T,TResult>

public class Compose2<T,TResult,TResult1,TResult2>
extends java.lang.Object
implements IFunc1Arg<T,TResult>

An adaptor that composes a binary function object f and two unary functions g1 and g2 into a unary function object h, such as h(x) is the same as f(g1(x), g2(x)).

Method Detail

Call

public TResult Call(T arg)

Composes a binary function object f and two unary functions g1 and g2 into a unary function object h, such as h(x) is the same as f(g1(x), g2(x)).

Specified by:

Call in interface IFunc1Arg<T,TResult>

Parameters:

arg - The argument used by both unary functions.

Returns:

The result of f(g1(arg), g2(arg)).
