Class MultiUserChatServiceImpl

java.lang.Object
  org.jivesoftware.openfire.muc.spi.MultiUserChatServiceImpl

All Implemented Interfaces:

DiscoInfoProvider, DiscoItemsProvider, ServerItemsProvider, MultiUserChatService, org.xmpp.component.Component

public class MultiUserChatServiceImpl
extends Object
implements org.xmpp.component.Component, MultiUserChatService, ServerItemsProvider, DiscoInfoProvider, DiscoItemsProvider

Implements the chat server as a cached memory resident chat server. The server is also responsible for responding Multi-User Chat disco requests as well as removing inactive users from the rooms after a period of time and to maintain a log of the conversation in the rooms that require to log their conversations. The conversations log is saved to the database using a separate process.

Temporary rooms are held in memory as long as they have occupants. They will be destroyed after the last occupant left the room. On the other hand, persistent rooms are always present in memory even after the last occupant left the room. In order to keep memory clean of persistent rooms that have been forgotten or abandoned this class includes a clean up process. The clean up process will remove from memory rooms that haven't had occupants for a while. Moreover, forgotten or abandoned rooms won't be loaded into memory when the Multi-User Chat service starts up.
