  • Method Details

    • values

      public static Direction[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static Direction 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

    • byId

      public static Direction byId​(int id) throws ArrayIndexOutOfBoundsException
      The Direction with this ID when expressed as an int.
      Parameters:
      id - ID of this Direction
      Returns:
      Direction with this ID
      Throws:
      ArrayIndexOutOfBoundsException - if the ID is not correct

    • byLabel

      public static Direction byLabel​(String label)
      The Direction with this label

      The current implementation assumes the labels are lower-case and words are separated by underscore (e.g., north_east).

      Parameters:
      label - Label of a direction
      Returns:
      A valid direction
      Throws:
      IllegalArgumentException - If no direction is found.
