Interface DistributedDoubleUnaryOperator

All Superinterfaces:

java.util.function.DoubleUnaryOperator, Serializable

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 DistributedDoubleUnaryOperator
extends java.util.function.DoubleUnaryOperator, Serializable

Represents an operation on a single double-valued operand that produces a double-valued result. This is the primitive type specialization of DistributedUnaryOperator for double.

This is a functional interface whose functional method is DoubleUnaryOperator.applyAsDouble(double).

Method Summary

Modifier and Type	Method and Description
default DistributedDoubleUnaryOperator	andThen(DistributedDoubleUnaryOperator after) Returns a composed operator that first applies this operator to its input, and then applies the after operator to the result.
default DistributedDoubleUnaryOperator	compose(DistributedDoubleUnaryOperator before) Returns a composed operator that first applies the before operator to its input, and then applies this operator to the result.
static DistributedDoubleUnaryOperator	identity() Returns a unary operator that always returns its input argument.

Method Detail

identity

static DistributedDoubleUnaryOperator identity()

Returns a unary operator that always returns its input argument.

Specified by:

identity in interface java.util.function.DoubleUnaryOperator

Returns:

a unary operator that always returns its input argument

compose

default DistributedDoubleUnaryOperator compose(DistributedDoubleUnaryOperator before)

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

Parameters:

before - the operator to apply before this operator is applied

Returns:

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

Throws:

NullPointerException - if before is null

See Also:

andThen(DistributedDoubleUnaryOperator)

andThen

default DistributedDoubleUnaryOperator andThen(DistributedDoubleUnaryOperator after)

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

Parameters:

after - the operator to apply after this operator is applied

Returns:

a composed operator that first applies this operator and then applies the after operator

Throws:

NullPointerException - if after is null
