@FunctionalInterface
public interface LongUnaryOperator
extends java.util.function.LongUnaryOperator

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 LongUnaryOperator	andThen(LongUnaryOperator after) Returns a composed function that first applies this function to its input, and then applies the after function to the result.
long	applyAsLong(long k) Type Specific get function to reduce boxing/unboxing
default LongUnaryOperator	compose(LongUnaryOperator before) Returns a composed function that first applies the before function to its input, and then applies this function to the result.
static LongUnaryOperator	identity() Creates a Default function that returns the input provided.

Method Detail

applyAsLong

long applyAsLong(long k)

Type Specific get function to reduce boxing/unboxing

Specified by:

applyAsLong in interface java.util.function.LongUnaryOperator

Parameters:

k - the value that should be processed

Returns:

the result of the function

identity

static LongUnaryOperator identity()

Creates a Default function that returns the input provided.

Specified by:

identity in interface java.util.function.LongUnaryOperator

Returns:

a input returning function

compose

default LongUnaryOperator compose(LongUnaryOperator 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.

Parameters:

before - the function that should be used first

Returns:

a composed function with a different starting function.

andThen

default LongUnaryOperator andThen(LongUnaryOperator 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 that should be used last

Returns:

a composed function with a different starting function.
