Method Detail

andThen

public static <T,U,R,V> BiFunction<T,U,V> andThen(BiFunction<? super T,? super U,? extends R> f1,
                                                  Function<? super R,? extends V> f2)

Composes BiFunction calls.

f2.apply(f1.apply(t, u))

Type Parameters:

T - the type of the first argument

U - the type of the second argument

R - the type of the result of the BiFunction f1

V - the type of the result of composed function f2

Parameters:

f1 - the BiFunction which is called first

f2 - the function for transform BiFunction f1 result to the type V

Returns:

the result of composed function

Throws:

NullPointerException - if f1 or f2 or result of BiFunction f1 is null

reverse

public static <T,U,R> BiFunction<U,T,R> reverse(BiFunction<? super T,? super U,? extends R> function)

Returns a BiFunction that reverses the input arguments order of the specified BiFunction.

Type Parameters:

T - the type of the first argument of the given function and the second argument of the reversed function

U - the type of the second argument of the given function and the first argument of the reversed function

R - the type of the result of the given function and of the reversed function

Parameters:

function - the BiFunction to reverse arguments

Returns:

the reversed function

Throws:

NullPointerException - if function is null
