  net.java.sip.communicator.impl.protocol.jabber.FailoverConnectionMonitor

All Implemented Interfaces:

EventListener, RegistrationStateChangeListener

public class FailoverConnectionMonitor
extends Object
implements RegistrationStateChangeListener

When provider registers, check whether we are connected to the first server in the dns records, if its not - considers in failover state and start a task that will periodically checks to see if server has come back and when this happens, re-register to it. If in the meanwhile, while in failover state the server we are connected became primary (became with highest priority in srv records) we consider ourselves out of failover state and stop all checks considering as we are connected to primary one.
