@FunctionalInterface public interface EventLostListener extends MapListener
Invoked upon lost of event or events. That event lost can be both a real or a possible event lost situation. In real event lost situation we can be sure that a sequence of events are missing and a recovery can be tried but in possible event lost situation we cannot be sure whether or not there is an event lost, for example, after a node is killed suddenly, we cannot be sure that all events on the killed node are sent and received by query caches.
