Examples of org.jivesoftware.smackx.packet.MessageEvent

org.jivesoftware.smackx.packet.MessageEvent
Represents message events relating to the delivery, display, composition and cancellation of messages.
There are four message events currently defined in this namespace:
1. Offline
  Indicates that the message has been stored offline by the intended recipient's server. This event is triggered only if the intended recipient's server supports offline storage, has that support enabled, and the recipient is offline when the server receives the message for delivery.
2. Delivered
  Indicates that the message has been delivered to the recipient. This signifies that the message has reached the recipient's XMPP client, but does not necessarily mean that the message has been displayed. This event is to be raised by the XMPP client.
3. Displayed
  Once the message has been received by the recipient's XMPP client, it may be displayed to the user. This event indicates that the message has been displayed, and is to be raised by the XMPP client. Even if a message is displayed multiple times, this event should be raised only once.
4. Composing
  In threaded chat conversations, this indicates that the recipient is composing a reply to a message. The event is to be raised by the recipient's XMPP client. A XMPP client is allowed to raise this event multiple times in response to the same request, providing the original event is cancelled first.
