Method Details

executeCommand

public void executeCommand(tigase.xmpp.jid.JID fromNode,
 Set<tigase.xmpp.jid.JID> visitedNodes,
 Map<String,String> data,
 Queue<tigase.xml.Element> packets)
                    throws tigase.cluster.api.ClusterCommandException

Method is responsible for processing request to synchronisation command. It creates a response packet(s) containing all users connection IDs (CIDs) on the given node and sends them back to node which originated the request. Records are split into smaller packet for performance reasons. If nor record is present a command with empty data is sent to allow setting correctly synchronised state.

Parameters:

fromNode - JID of the originating node from which request came.

visitedNodes - Set containing JID of all already visited nodes

data - additional data

packets - Queue holding all originally received packets.

Throws:

tigase.cluster.api.ClusterCommandException
