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

    UnaryOperator
    • Method Detail

      • apply

        boolean apply​(boolean x)
        Computes the operator on the given input.
        Parameters:
        x - the input.
        Returns:
        the output of the operator on the given input.
      • identity

        static BooleanUnaryOperator identity()
        Returns a UnaryOperator that always returns the input unmodified.
        See Also:
        UnaryOperator.identity()
      • negation

        static BooleanUnaryOperator negation()
        Returns a UnaryOperator that always returns the logical negation of the input.
      • apply

        @Deprecated
        default java.lang.Boolean apply​(java.lang.Boolean x)
        Deprecated.
        Please use the corresponding type-specific method instead.
