| /** |
| * Packet interceptor that will intercept presence packets sent to the MUC service to indicate |
| * that the user wants to be a deaf occupant. A user can only indicate that he wants to be a |
| * deaf occupant while joining the room. It is not possible to become deaf or stop being deaf |
| * after the user joined the room.<p> |
| * |
| * Deaf occupants will not get messages broadcasted to all room occupants. However, they will |
| * be able to get private messages, presences, IQ packets or room history. To use this |
| * functionality you will need to send the message |
| * {@link MultiUserChat#addPresenceInterceptor(org.jivesoftware.smack.PacketInterceptor)} and |
| * pass this interceptor as the parameter.<p> |
| * |
| * Note that this is a custom extension to the MUC service so it may not work with other servers |
| * than Wildfire. |
