Interface LongUnaryOperator

All Superinterfaces:

java.util.function.Function<java.lang.Long,java.lang.Long>, java.util.function.LongUnaryOperator, java.util.function.UnaryOperator<java.lang.Long>

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 LongUnaryOperator
extends java.util.function.UnaryOperator<java.lang.Long>, java.util.function.LongUnaryOperator

A type-specific UnaryOperator; provides methods operating both on objects and on primitives.

Since:

8.5.0

Method Summary

Modifier and Type	Method and Description
long	apply(long x) Computes the operator on the given input.
default java.lang.Long	apply(java.lang.Long x) Deprecated. Please use the corresponding type-specific method instead.
default long	applyAsLong(long x) Deprecated. Please use apply(long).
static LongUnaryOperator	identity() Returns a UnaryOperator that always returns the input unmodified.
static LongUnaryOperator	negation() Returns a UnaryOperator that always returns the arithmetic negation of the input.
