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

      Modifier and Type Method 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)

      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.

      • apply

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

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

        static IntUnaryOperator negation()
        Returns a UnaryOperator that always returns the arithmetic negation of the input.
        Implementation Notes:
        As with all negation, be wary of unexpected behavior near the minimum value of the data type. For example, -Integer.MIN_VALUE will result in Integer.MIN_VALUE (still negative), as the positive value of Integer.MIN_VALUE is too big for int (it would be 1 greater then Integer.MAX_VALUE).
