extends java.lang.Object

The Mango Library Binary Functions

A BinaryFunction is some function taking two arguments - fn(T1 x, T2 y). It returns some R, and may return the same object or different objects for each invocation, even given the same arguments. It can refer to local state, perform disk reads or writes, or whatever.

Method Detail

Compose

public static <T1,R1,T2,R2,R> BinaryFunction<T1,T2,R> Compose(BinaryFunction<R1,R2,R> f,
                                                              Function<T1,R1> g1,
                                                              Function<T2,R2> g2)

Compose is a function adaptor. If f is a BinaryFunction and g1 and g2 are Functions, then Compose returns a new BinaryFunction h such that h(x, y) is f(g1(x), g2(y))
