Method Detail

First

public static UnaryFunction First(BinaryFunction f,
                                  java.lang.Object c)

Adapts a BinaryFunction into a UnaryFunction. If f is an object implementing BinaryFunction, then Bind.First(f, C).fn(arg) returns f(C, arg).

Intuitively, you can think of this as "binding" the first argument of a BinaryFunction to a constant, thus giving a UnaryFunction.

First

public static Predicate First(BinaryPredicate p,
                              java.lang.Object c)

Special case which adapts a BinaryPredicate to a Predicate. If p is a BinaryPredicate, then Bind.First(p, C).test(arg) returns p.test(C, arg).

Second

public static UnaryFunction Second(BinaryFunction f,
                                   java.lang.Object c)

Adapts a BinaryFunction into a UnaryFunction. If f is an object implementing BinaryFunction, then Bind.Second(f, C).fn(arg) returns f(arg, C).

Intuitively, you can think of this as "binding" the second argument of a BinaryFunction to a constant, thus giving a UnaryFunction.

Second

public static Predicate Second(BinaryPredicate p,
                               java.lang.Object c)

Special case which adapts a BinaryPredicate to a Predicate. If p is a BinaryPredicate, then Bind.Second(p, C).test(arg) returns p.test(arg, C).
