    • Method Detail

      • fromJournal

        EventSeq fromJournal​(java.lang.Object event,
                             java.lang.String manifest)
        Convert a event from its journal model to the applications domain model.

        One event may be adapter into multiple (or none) events which should be delivered to the PersistentActor. Use the specialised EventSeq.single(java.lang.Object) method to emit exactly one event, or EventSeq.empty() in case the adapter is not handling this event. Multiple EventAdapter instances are applied in order as defined in configuration and their emitted event seqs are concatenated and delivered in order to the PersistentActor.

        Parameters:
        event - event to be adapted before delivering to the PersistentActor
        manifest - optionally provided manifest (type hint) in case the Adapter has stored one for this event, "" if none
        Returns:
        sequence containing the adapted events (possibly zero) which will be delivered to the PersistentActor
