Type Members

1. case class LoadSnapshot(emitterId: String, requestor: ActorRef, instanceId: Int) extends Product with Serializable

   

   Instructs an event log to load the most recent snapshot for requestor identified by emitterId.

2. case class LoadSnapshotFailure(cause: Throwable, instanceId: Int) extends Product with Serializable

   

   Failure reply after a LoadSnapshot.

3. case class LoadSnapshotSuccess(snapshot: Option[Snapshot], instanceId: Int) extends Product with Serializable

   

   Success reply after a LoadSnapshot.

4. case class Replay(from: Long, requestor: ActorRef, aggregateId: Option[String], instanceId: Int) extends Product with Serializable

   

   Instructs an event log to replay events from sequence number from to the given requestor.

   Instructs an event log to replay events from sequence number from to the given requestor. Replayed events are sent within Replaying messages. If replay successfully completes the event log must additionally send a ReplaySuccess message, otherwise, a ReplayFailure message.

   If aggregateId is defined, only events with a matching aggregateId are replayed, otherwise, all events.

5. case class ReplayFailure(cause: Throwable, instanceId: Int) extends Product with Serializable

   

   Failure reply after a Replay.

6. case class ReplaySuccess(instanceId: Int) extends Product with Serializable

   

   Success reply after a Replay, sent when all Replaying messages have been sent.

7. case class Replaying(event: DurableEvent, instanceId: Int) extends Product with Serializable

   

   Single event replay after a Replay.

8. case class SaveSnapshot(snapshot: Snapshot, initiator: ActorRef, requestor: ActorRef, instanceId: Int) extends Product with Serializable

   

   Instructs an event log to save the given snapshot.

9. case class SaveSnapshotFailure(metadata: SnapshotMetadata, cause: Throwable, instanceId: Int) extends Product with Serializable

   

   Failure reply after a SaveSnapshot.

10. case class SaveSnapshotSuccess(metadata: SnapshotMetadata, instanceId: Int) extends Product with Serializable

    

    Success reply after a SaveSnapshot.

11. case class Write(events: Seq[DurableEvent], initiator: ActorRef, requestor: ActorRef, instanceId: Int) extends Product with Serializable

    

    Instructs an event log to write the given events and send the written events one-by-one to the given requestor.

    Instructs an event log to write the given events and send the written events one-by-one to the given requestor. In case of a successful write, events are sent within WriteSuccess messages, otherwise within WriteFailure messages with initiator as message sender.

12. case class WriteFailure(event: DurableEvent, cause: Throwable, instanceId: Int) extends Product with Serializable

    

    Failure reply after a Write.

13. case class WriteN(writes: Seq[Write]) extends Product with Serializable

    

    Instructs an event log to batch-execute the given writes.

14. case class WriteSuccess(event: DurableEvent, instanceId: Int) extends Product with Serializable

    

    Success reply after a Write.

15. case class Written(event: DurableEvent) extends Product with Serializable

    

    Sent by an event log to all registered participants, if event has been successfully written.

    Sent by an event log to all registered participants, if event has been successfully written. This message is not sent to a participant if that participant has sent a corresponding Write.
