Interface BooleanUnaryOperator

All Superinterfaces:
java.util.function.Function<java.lang.Boolean,​java.lang.Boolean>, java.util.function.UnaryOperator<java.lang.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 java.util.function.UnaryOperator<java.lang.Boolean>
A type-specific UnaryOperator; provides methods operating both on objects and on primitives.
Since:
8.5.0
