void ServiceList::ProcessServerList ( )

private

This function processes the update of the DIS_DNS/SERVER_LIST update. After this function the server list should be up-to-date again.

For each new server a SERVER/SERVICE_LIST service subscription is created and stored in the fServerList. For each removed server the corresponding object are deleted, as well as the corresponding entries from the fServiceList.
