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

Returns a composed function that first applies the this_ function to its inputs, and then applies the after function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.

Type Parameters:

R - the type of the result of the this_ function and the type of the input of the after function.

T - the type of the first argument to the this_ function

U - the type of the second argument to the this_ function

V - the type of output of the after function, and of the composed function

Parameters:

this_ - the BiFunction to be applied first.

after - the function to apply after the this_ function is applied

Returns:

a composed function that first applies the this_ function and then applies the after function

Throws:

java.lang.NullPointerException - if this_ is null

java.lang.NullPointerException - if after is null
