      public boolean needsSync()
      Allow obtaining information whether cache needs synching with other nodes.
      Returns:
      true if cache is out of synch, false otherwise.

    • setSync

      public void setSync(boolean sync)
      Set the state of synchronisation.
      Specified by:
      setSync in interface CacheContenerIfc
      Parameters:
      sync - boolean value denoting sync state.

    • removeAllForNode

      public void removeAllForNode(tigase.xmpp.jid.JID node)
      Method removes all cached connections which were related to the given node (e.g. when the node was disconnected) as well as decreases count of all connections stored in cache.
      Specified by:
      removeAllForNode in interface CacheContenerIfc
      Parameters:
      node - JID of the node for which cached items will be removed.

    • updatePresence

      public void updatePresence(tigase.xml.Element presence, ConnectionRecordExt rec)
      Method updates given connection in the cache with the information about presence for the given connection.
      Parameters:
      presence - Element containing presence information
      rec - ConnectionRecordExt for which presence should be updated

    • userDisconnected

      public void userDisconnected(ConnectionRecordExt rec)
      Method responsible for user disconnection events. Removes given connection record from the cache and decrease counter of all connections.
      Specified by:
      userDisconnected in interface CacheContenerIfc
      Parameters:
      rec - ConnectionRecordExt for which presence should be updated

    • usersConnected

      public void usersConnected(ConnectionRecordExt... recs)
      Method responsible for user connection events. Adds given connection record to the cache and increases counters of both all connections and number of user JIDs in cache..
      Specified by:
      usersConnected in interface CacheContenerIfc
      Parameters:
      recs - ConnectionRecordExt for which presence should be updated

    • userChangedConnId

      public void userChangedConnId(tigase.xmpp.jid.BareJID userId, tigase.xmpp.jid.JID oldConnectionId, tigase.xmpp.jid.JID newConnectionId)
      Method responsible for replacing used conn id by user connection/resource. In fact it removes connection using old connection id from connection cache, updates internal value of connection id to new connection id and adds it to cache using new connection id as a key.

      This happens during stream resumption as connection id changes for session for which stream is resumed.

      Parameters:
      userId - - bare jid of user
      oldConnectionId - - connection id which was changed
      newConnectionId - - connection id which replaced old connection id

      Retrieves a ConnectionRecordExt for the particular, specific JID
      Specified by:
      getConnectionRecord in interface CacheContenerIfc
      Parameters:
      jid - for which ConnectionRecordExt should be retrieved
      Returns:
