Funktionsschnittstelle:

Dies ist eine funktionale Schnittstelle, die somit als Zuweisungsziel für einen Lambdaausdruck oder eine Methodenreferenz verwendet werden kann.

@FunctionalInterface
public interface DoubleUnaryOperator
extends DoubleUnaryOperator

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

Methodenübersicht

Modifizierer und Typ	Methode	Beschreibung
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.

Methodendetails

applyAsDouble

double applyAsDouble(double k)

Type Specific get function to reduce boxing/unboxing

Angegeben von:

applyAsDouble in Schnittstelle DoubleUnaryOperator

Parameter:

k - the value that should be processed

Gibt zurück:

the result of the function

identity

static DoubleUnaryOperator identity()

Creates a Default function that returns the input provided.

Gibt zurück:

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.

Parameter:

before - the function that should be used first

Gibt zurück:

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.

Parameter:

after - the function that should be used last

Gibt zurück:

a composed function with a different starting function.
