Interface IBiFunction<T,U,R>

Type Parameters:

T - the type of the first argument to the function

U - the type of the second argument to the function

R - the type of the result of the function

All Superinterfaces:

BiFunction<T,U,R>, Serializable

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface IBiFunction<T,U,R>
extends BiFunction<T,U,R>, Serializable

Represents a function that accepts two arguments and produces a result. This is the two-arity specialization of Function.

This is a functional interface whose functional method is BiFunction.apply(Object, Object).

Since:

8.6.3

Method Summary

Modifier and Type	Method and Description
default <V> IBiFunction<T,U,V>	andThen(Function<? super R,? extends V> aAfter) Returns a composed function that first applies this function to its input, and then applies the after function to the result.

Method Detail

andThen

@Nonnull
default <V> IBiFunction<T,U,V> andThen(@Nonnull
                                                 Function<? super R,? extends V> aAfter)

Returns a composed function that first applies this function to its input, 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.

Specified by:

andThen in interface BiFunction<T,U,R>

Type Parameters:

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

Parameters:

aAfter - the function to apply after this function is applied

Returns:

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

Throws:

NullPointerException - if after is null
