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 static interface Remote.Function<T,R>
extends Function<T,R>, Serializable

Represents a function that accepts one argument and produces a result.

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

Method Summary

Modifier and Type	Method	Description
default <V> Remote.Function<T,V>	andThen(Remote.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.
default <V> Remote.Function<V,R>	compose(Remote.Function<? super V,? extends T> before)	Returns a composed function that first applies the before function to its input, and then applies this function to the result.
static <T> Remote.Function<T,T>	identity()	Returns a function that always returns its input argument.

Method Detail

compose

default <V> Remote.Function<V,R> compose(Remote.Function<? super V,? extends T> before)

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

Type Parameters:

V - the type of input to the before function, and to the composed function

Parameters:

before - the function to apply before this function is applied

Returns:

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

Throws:

NullPointerException - if before is null

andThen(Function)

andThen

default <V> Remote.Function<T,V> andThen(Remote.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.

Type Parameters:

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

compose(Function)

identity

static <T> Remote.Function<T,T> identity()

Returns a function that always returns its input argument.

Type Parameters:

T - the type of the input and output objects to the function

Returns:

a function that always returns its input argument
