  - ### Method Detail

    - #### values

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

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

    - #### valueOf

          public static MessageType 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

    - #### getText

          public String getText()

      Returns:
        text representation of the `Message`

    - #### from

          public static MessageType from​(String type)

      Get a `MessageType` from its text representation.
      Parameters:
        `type` - the message type text representation
      Returns:
        the corresponding message type or null if none matches
