    - #### ASCENDING

          public static final QuerySort.SortDirection ASCENDING

      Ascending (A-Z, 1..9) sort order

    - #### DESCENDING

          public static final QuerySort.SortDirection DESCENDING

      Descending (Z-A, 9..1) sort order

  - ### Method Detail

    - #### values

          public static QuerySort.SortDirection[] 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 (QuerySort.SortDirection c : QuerySort.SortDirection.values())
              System.out.println(c);

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

    - #### valueOf

          public static QuerySort.SortDirection 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

    - #### getOpposite

          public abstract QuerySort.SortDirection getOpposite()

      Direct opposite sort direction
      Returns:
        Opposite sort direction
