|
|
* Represents XMPP message packets. A message can be one of several types:
|
|
*
|
|
* <ul>
|
|
* <li>Message.Type.NORMAL -- (Default) a normal text message used in email like interface.
|
|
* <li>Message.Type.CHAT -- a typically short text message used in line-by-line chat interfaces.
|
|
* <li>Message.Type.GROUP_CHAT -- a chat message sent to a groupchat server for group chats.
|
|
* <li>Message.Type.HEADLINE -- a text message to be displayed in scrolling marquee displays.
|
|
* <li>Message.Type.ERROR -- indicates a messaging error.
|
