All Implemented Interfaces:

java.io.Serializable, Visitable

public class Bind2nd<T1,T2,R>
extends UnaryFunctor<T1,R>

UnaryFunctor that wraps a given BinaryFunctor, passing a constant value as the second argument of the child functor. The runtime argument is passed as the first argument of the child functor.
