Interface SubscriptionStore.Listener

All Known Implementing Classes:
PushEvents
Enclosing class:
SubscriptionStore
public static interface SubscriptionStore.Listener
Observer of the rows this store creates and removes (P4-04): called on the thread that made the change, after its transaction committed, once per row. An implementation must not block - the engine's PushEvents only posts to session workers - and one that throws is logged and does not stop the others or the caller.
