        Description copied from class: EventAdapter
        Transform the event on recovery from the journal. Note that this is not called in any read side so will need to be applied manually when using Query.

        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 EventSourcedBehavior. Use the specialised EventSeq.single method to emit exactly one event, or EventSeq.empty in case the adapter is not handling this event.
