Method Detail

First

public static <T1,T2,R> Function<T2,R> First(BinaryFunction<T1,T2,R> f,
                                             T1 c)

Adapts a BinaryFunction into a Function. 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 Function.

First

public static <T1,T2> Predicate<T2> First(BinaryPredicate<T1,T2> p,
                                          T1 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 <T1,T2,R> Function<T1,R> Second(BinaryFunction<T1,T2,R> f,
                                              T2 c)

Adapts a BinaryFunction into a Function. 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 Function.

Second

public static <T1,T2> Predicate<T1> Second(BinaryPredicate<T1,T2> p,
                                           T2 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).
