  - ### Method Detail

    - #### hashCodeForPacket

          public int hashCodeForPacket(Packet packet)

      Description copied from class: `AbstractMessageReceiver`
      This method decides how incoming packets are distributed among processing threads. Different components needs different distribution to efficient use all threads and avoid packets re-ordering.
      If there are N processing threads, packets are distributed among threads using following code:

           int threadNo = Math.abs(hashCodeForPacket(packet) % N);

      For a PubSub component, for example, a better packets distribution would be based on the PubSub channel name, for SM a better distribution is based on the destination address, etc....
      Overrides:
        `hashCodeForPacket` in class `ConnectionManager<XMPPIOService<Object>>`
      Parameters:
        `packet` - is a `Packet` which needs to be processed by some thread.
      Returns:
        a hash code generated for the input thread.

    - #### initBindings

      Overrides:
        `initBindings` in class `ConnectionManager<XMPPIOService<Object>>`
      Parameters:
        `binds` - A mapping of key/value pairs, all of whose keys are Strings.

          public void nodeDisconnected(String node)

      Description copied from interface: `ClusteredComponentIfc`
      Method is called on cluster node disconnection event. This is a notification to the component that there was network connection lost to one of the cluster nodes.
      Specified by:
        `nodeDisconnected` in interface `ClusteredComponentIfc`
      Parameters:

    - #### processingInThreads

          public int processingInThreads()

      Description copied from class: `AbstractMessageReceiver`
      Concurrency control method. Returns preferable number of threads set for this component.
      Overrides:
        `processingInThreads` in class `ConnectionManager<XMPPIOService<Object>>`
      Returns:
        preferable number of threads set for this component.

    - #### processingOutThreads

          public int processingOutThreads()

      Description copied from class: `AbstractMessageReceiver`
      Concurrency control method. Returns preferable number of threads set for this component.
      Overrides:
        `processingOutThreads` in class `ConnectionManager<XMPPIOService<Object>>`
      Returns:
        preferable number of threads set for this component.

    - #### processOutPacket

          public void processOutPacket(Packet packet)

      Description copied from class: `AbstractMessageReceiver`
      By default this method just copies the given packet between queue. This method operates on packets which have been already processed somehow by the component so usually the default action is the best one, however some components in rare cases may choose to process packets differently. In most cases this method should not be overridden.
      Overrides:
        `processOutPacket` in class `AbstractMessageReceiver`
      Parameters:
        `packet` - is an output packet which normally has to go to other component for further processing.

    - #### processPacket

          public void processPacket(Packet packet)

      Description copied from class: `AbstractMessageReceiver`
      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.
      Overrides:
        `processPacket` in class `ConnectionManager<XMPPIOService<Object>>`
      Parameters:
        `packet` - is an instance of the `Packet` class passed for processing.

    - #### processSocketData

          public Queue<Packet> processSocketData(XMPPIOService<Object> serv)

      Description copied from class: `ConnectionManager`
      Method description
      Specified by:
        `processSocketData` in class `ConnectionManager<XMPPIOService<Object>>`
      Returns:
        a value of `Queue<Packet>`

    - #### reconnectionFailed

          public void reconnectionFailed(Map<String,Object> port_props)

      Description copied from class: `ConnectionManager`

      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 `ConnectionManager<XMPPIOService<Object>>`
      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.

    - #### 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.
