BiFunction

public interface BiFunction

java.util.function.BiFunction<T, U, R>

Known indirect subclasses

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(java.lang.Object, java.lang.Object).

Summary

Public methods
`default <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

andThen

Added in API level 24

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`	`Function`: the function to apply after this function is applied

Returns
`BiFunction<T, U, V>`	a composed function that first applies this function and then applies the `after` function

Throws
`NullPointerException`	if after is null

apply

Added in API level 24

public abstract R apply (T t, 
                U u)

Applies this function to the given arguments.

Parameters
`t`	`T`: the first function argument
`u`	`U`: the second function argument

Returns
`R`	the function result
