Interface ShortUnaryOperator

All Superinterfaces:
Function<Short,Short>, IntUnaryOperator, UnaryOperator<Short>
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 ShortUnaryOperator extends UnaryOperator<Short>, IntUnaryOperator
A type-specific UnaryOperator; provides methods operating both on objects and on primitives.
Since:
8.5.0

  • Method Summary

    Modifier and Type
    Method
    Description
    short
    apply(short x)
    Computes the operator on the given input.
    default Short
    apply(Short x)
    Deprecated.
    Please use the corresponding type-specific method instead.
    default int
    applyAsInt(int x)
    Deprecated.
    Please use apply(short).
    static ShortUnaryOperator
    identity()
    Returns a UnaryOperator that always returns the input unmodified.
    static ShortUnaryOperator
    negation()
    Returns a UnaryOperator that always returns the arithmetic negation of the input.

  • Method Details

    • apply

      short apply(short x)
      Computes the operator on the given input.
      Parameters:
      x - the input.
      Returns:
      the output of the operator on the given input.

    • identity

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

    • negation

      static ShortUnaryOperator 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).

    • applyAsInt

      @Deprecated default int applyAsInt(int x)
      Deprecated.
      Please use apply(short).
      Specified by:
      applyAsInt in interface IntUnaryOperator
      Throws:
      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(short) 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.

    • apply

      @Deprecated default Short apply(Short x)
      Deprecated.
      Please use the corresponding type-specific method instead.
      Specified by:
      apply in interface Function<Short,Short>
