Known Indirect Subclasses BinaryOperator<T> BinaryOperator<T> Represents an operation upon two operands of the same type, producing a result of the same type as the operands.

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 apply(Object, Object).

Public Method Summary

<V> BiFunction<T, U, V>	andThen(Function<? super R, ? extends V> after) Returns a composed function that first applies this function to its input, and then applies the after function to the result.
abstract R	apply(T t, U u) Applies this function to the given arguments.

Public Methods

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

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.

Parameters

after	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

public abstract R apply (T t, U u)

Applies this function to the given arguments.

Parameters

t	the first function argument
u	the second function argument

Returns

• the function result
