Interface Distributed.LongUnaryOperator

All Superinterfaces:

java.util.function.LongUnaryOperator, Serializable

Enclosing class:

Distributed

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 static interface Distributed.LongUnaryOperator
extends java.util.function.LongUnaryOperator, Serializable

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

This is a functional interface whose functional method is LongUnaryOperator.applyAsLong(long).

Distributed.UnaryOperator

Method Summary

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

Method Detail

compose

default Distributed.LongUnaryOperator compose(Distributed.LongUnaryOperator 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

LongUnaryOperator.andThen(LongUnaryOperator)

andThen

default Distributed.LongUnaryOperator andThen(Distributed.LongUnaryOperator 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

LongUnaryOperator.compose(LongUnaryOperator)

identity

static Distributed.LongUnaryOperator identity()

Returns a unary operator that always returns its input argument.

Specified by:

identity in interface java.util.function.LongUnaryOperator

Returns:

a unary operator that always returns its input argument
