Interface CharUnaryOperator

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

      • apply

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

        static CharUnaryOperator identity()
        Returns a UnaryOperator that always returns the input unmodified.

      • applyAsInt

        @Deprecated
        default int applyAsInt​(int x)
        Deprecated.
        Please use apply(char).
        Specified by:
        applyAsInt in interface java.util.function.IntUnaryOperator
        Throws:
        java.lang.IllegalArgumentException - If the given operands are not an element of the key domain.
        Since:
        8.5.0
        Implementation Specification:
        This default implementation delegates to apply(char) after narrowing down the argument to the actual key type, throwing an exception if the argument cannot be represented in the restricted domain. This is done for interoperability with the Java 8 function environment. The use of this method discouraged, as unexpected errors can occur.
