public abstract class SingleActiveServiceKrouter<T extends SingleActiveServiceKrouter>
extends AbstractKrouter<T>

Created by ruedi on 13.03.17. Simply forwards all incoming calls to the registered Service. If a new service registers, it replaces the previous one. If a service is 'stateful', clients stick to their initial connected service instance as long it is available. Only once the initially connected service instance becomes unavailable, clients receive a failovernotification to re-establish state (e.g. subscriptions).
