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 UnaryOperator<T,V>
extends java.util.function.Function<T,V>

A Type Specific Function interface that reduces boxing/unboxing and fills the gaps of interfaces that are missing.

Method Summary

Modifier and Type	Method and Description
default <I> UnaryOperator<T,I>	andThen(UnaryOperator<V,I> after) Returns a composed function that first applies this function to its input, and then applies the after function to the result.
V	apply(T k) Type Specific get function to reduce boxing/unboxing
default <I> UnaryOperator<I,V>	compose(UnaryOperator<I,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> UnaryOperator<T,T>	identity() Creates a Default function that returns the input provided.

Method Detail

apply

V apply(T k)

Type Specific get function to reduce boxing/unboxing

Specified by:

apply in interface java.util.function.Function<T,V>

Parameters:

k - the value that should be processed

Returns:

the result of the function

identity

static <T> UnaryOperator<T,T> identity()

Creates a Default function that returns the input provided.

Specified by:

identity in interface java.util.function.Function<T,V>

Type Parameters:

T - the keyType of elements maintained by this Collection

Returns:

a input returning function

compose

default <I> UnaryOperator<I,V> compose(UnaryOperator<I,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:

I - the keyType of elements maintained by this Collection

Parameters:

before - the function that should be used first

Returns:

a composed function with a different starting function.

andThen

default <I> UnaryOperator<T,I> andThen(UnaryOperator<V,I> 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:

I - the keyType of elements maintained by this Collection

Parameters:

after - the function that should be used last

Returns:

a composed function with a different starting function.
