Interface IntUnaryOperator

All Superinterfaces:

java.util.function.Function<java.lang.Integer,java.lang.Integer>, java.util.function.IntUnaryOperator, java.util.function.UnaryOperator<java.lang.Integer>

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 IntUnaryOperator
extends java.util.function.UnaryOperator<java.lang.Integer>, java.util.function.IntUnaryOperator

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
int	apply(int x) Computes the operator on the given input.
default java.lang.Integer	apply(java.lang.Integer x) Deprecated. Please use the corresponding type-specific method instead.
default int	applyAsInt(int x) Deprecated. Please use apply(int).
static IntUnaryOperator	identity() Returns a UnaryOperator that always returns the input unmodified.
static IntUnaryOperator	negation() Returns a UnaryOperator that always returns the arithmetic negation of the input.
