Interface BooleanUnaryOperator

All Superinterfaces:

Function<Boolean,Boolean>, UnaryOperator<Boolean>

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 BooleanUnaryOperator
extends UnaryOperator<Boolean>

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

Since:

8.5.0

Method Summary

Modifier and Type	Method	Description
boolean	apply(boolean x)	Computes the operator on the given input.
default Boolean	apply(Boolean x)	Deprecated. Please use the corresponding type-specific method instead.
static BooleanUnaryOperator	identity()	Returns a UnaryOperator that always returns the input unmodified.
static BooleanUnaryOperator	negation()	Returns a UnaryOperator that always returns the logical negation of the input.
