    - #### MINUS

          public static final UnaryOperator MINUS

    - #### NOT

          public static final UnaryOperator NOT

  - ### Method Detail

    - #### values

          public static UnaryOperator[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (UnaryOperator c : UnaryOperator.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static UnaryOperator valueOf(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
        `name` - the name of the enum constant to be returned.
      Returns:
        the enum constant with the specified name
      Throws:
        `IllegalArgumentException` - if this enum type has no constant with the specified name
        `NullPointerException` - if the argument is null

    - #### toString

          public String toString()

      Overrides:
        `toString` in class `Enum<UnaryOperator>`
      Returns:
        Methods name for usage in in text

    - #### toUriLiteral

          public String toUriLiteral()

      Returns:
        Syntax of the unary operator as used in the URL.
