        preferable number of threads set for this component.

    - #### processPacket

          public void processPacket(Packet packet)

      This is the main `Packet` processing method. It is called concurrently from many threads so implementing it in thread save manner is essential. The method is called for each packet addressed to the component.
      Please note, the `Packet` instance may be processed by different parts of the server, different components or plugins at the same time. Therefore this is very important to tread the `Packet` instance as unmodifiable object.
      Processing in this method is asynchronous, therefore there is no result value. If there are some 'result' packets generated during processing, they should be passed back using `addOutPacket(Packet)` method.
      This is a standard component method for processing packets. The method takes care of cases where the packet cannot be processed locally, in such a case it is forwarded to another node.
      Overrides:
        `processPacket` in class `SessionManager`
      Parameters:
        `packet` - to be processed

    - #### processPacket

      Method description
      Specified by:
        `processPresenceUpdate` in interface `SessionManagerClusteredIfc`
      Overrides:
        `processPresenceUpdate` in class `SessionManager`

      Overrides:
        `getComponentInfo` in class `BasicComponent`
      Returns:

    - #### getConnectionIdsForJid

          public tigase.xmpp.JID[] getConnectionIdsForJid(tigase.xmpp.BareJID jid)

      Retrieve all connection IDs (CIDs) for the given user.
      If the installation knows about user's JID, that he is connected to the system, then this method returns all user's connection IDs. As an optimization we can forward packets to all user's connections directly from a single node.
      Specified by:
        `getConnectionIdsForJid` in interface `OnlineJidsReporter`
      Overrides:
        `getConnectionIdsForJid` in class `SessionManager`
      Parameters:
        `jid` - a user's JID for whom we query information.
      Returns:
        a list of all user's connection IDs.

    - #### getDefaults

          public Map<String,Object> getDefaults(Map<String,Object> params)

      Description copied from class: `AbstractMessageReceiver`
      Returns default configuration settings for the component as a `Map` with keys as configuration property IDs and values as the configuration property values. All the default parameters returned from this method are later passed to the `setProperties(...)` method. Some of them may have changed value if they have been overwritten in the server configuration. The configuration property value can be of any of the basic types: `int`, `long`, `boolean`, `String`.
      Specified by:
        `getDefaults` in interface `Configurable`
      Overrides:
        `getDefaults` in class `SessionManager`
      Parameters:
        `params` - is a `Map` with some initial properties set for the starting up server. These parameters can be used as a hints to generate component's default configuration.
      Returns:
        a `Map` with the component default configuration.

    - #### getDiscoDescription

          public String getDiscoDescription()

      Description copied from class: `BasicComponent`
      Method description
      Overrides:
        `getDiscoDescription` in class `SessionManager`
      Returns:
        a value of `String`

    - #### getStatistics

          public void getStatistics(StatisticsList list)

      Description copied from class: `AbstractMessageReceiver`
      Method returns component statistics. Please note, the method can be called every second by the server monitoring system therefore no extensive or lengthy calculations are allowed. If there are some statistics requiring lengthy operations like database access they must have `Level.FINEST` assigned and must be put inside the level guard to prevent generating them by the system monitor. The system monitor does not collect `FINEST` statistics.
      Level guard code looks like the example below:

           if (list.checkLevel(Level.FINEST)) {
             // Some CPU intensive calculations or lengthy operations
             list.add(getName(), "Statistic description", stat_value, Level.FINEST);
           }

      This way you make sure your extensive operation is not executed every second by the monitoring system and does not affect the server performance.
      Specified by:
        `getStatistics` in interface `StatisticsContainer`
      Overrides:
        `getStatistics` in class `SessionManager`
      Parameters:
        `list` - is a `StatistcsList` where all statistics are stored.

    - #### getStrategy
