    - #### getStatistics

          public void getStatistics(StatisticsList list)

      Returns statistics generated by this processor
      Specified by:
        `getStatistics` in interface `XMPPIOProcessor`

    - #### streamError

          public void streamError(XMPPIOService service,
                                  StreamError streamErrorName)

      Description copied from interface: `XMPPIOProcessor`
      Method called when XMPP stream error is about to be sent
      Specified by:
        `streamError` in interface `XMPPIOProcessor`

    - #### shouldRequestAck

          protected boolean shouldRequestAck(XMPPIOService service,
                                             StreamManagementIOProcessor.OutQueue outQueue)

      Override this method to define a custom behaviour for request ack. The default implementation will request an ack if there are more than `ack_request_count` packets waiting, so you probably want to OR your behaviour with this.

    - #### newCounter

          protected StreamManagementIOProcessor.Counter newCounter()

    - #### newOutQueue

          protected StreamManagementIOProcessor.OutQueue newOutQueue()
