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

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

Method Detail

applyAsDouble

double applyAsDouble(double k)

Type Specific get function to reduce boxing/unboxing

Specified by:

applyAsDouble in interface java.util.function.DoubleUnaryOperator

Parameters:

k - the value that should be processed

Returns:

the result of the function

identity

static DoubleUnaryOperator identity()

Creates a Default function that returns the input provided.

Specified by:

identity in interface java.util.function.DoubleUnaryOperator

Returns:

a input returning function

compose

default DoubleUnaryOperator compose(DoubleUnaryOperator 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 DoubleUnaryOperator andThen(DoubleUnaryOperator 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.
