      • context

        public ActorContext context()
        Description copied from interface: Actor
        Scala API: Stores the context for this actor, including self, and sender. It is implicit to support operations such as forward.

        WARNING: Only valid within the Actor itself, so do not close over it and publish it to other threads!

        pekko.actor.ActorContext is the Scala API. getContext returns a pekko.actor.AbstractActor.ActorContext, which is the Java API of the actor context.

        context in interface Actor
      • deleteAsync

        public final scala.concurrent.Future<scala.runtime.BoxedUnit> deleteAsync​(SnapshotMetadata metadata)
        Description copied from interface: SnapshotStore
        Plugin API: deletes the snapshot identified by metadata.

        This call is protected with a circuit-breaker.

        Specified by:
        deleteAsync in interface SnapshotStore
        Parameters:
        metadata - snapshot metadata.
      • deleteAsync

        public final scala.concurrent.Future<scala.runtime.BoxedUnit> deleteAsync​(java.lang.String persistenceId,
                                                                                  SnapshotSelectionCriteria criteria)
        Description copied from interface: SnapshotStore
        Plugin API: deletes all snapshots matching criteria.

        This call is protected with a circuit-breaker.

        Specified by:
        deleteAsync in interface SnapshotStore
        Parameters:
        persistenceId - id of the persistent actor.
        criteria - selection criteria for deleting.
      • loadAsync

        public final scala.concurrent.Future<scala.Option<SelectedSnapshot>> loadAsync​(java.lang.String persistenceId,
                                                                                       SnapshotSelectionCriteria criteria)
        Description copied from interface: SnapshotStore
        Plugin API: asynchronously loads a snapshot.

        If the future Option is None then all events will be replayed, i.e. there was no snapshot. If snapshot could not be loaded the Future should be completed with failure. That is important because events may have been deleted and just replaying the events might not result in a valid state.

        This call is protected with a circuit-breaker.

        Specified by:
        loadAsync in interface SnapshotStore
        Parameters:
        persistenceId - id of the persistent actor.
        criteria - selection criteria for loading.
