Abstract Value Members

  1. abstract def fromJournal(event: Any, manifest: String): EventSeq

    Permalink

    Convert a event from its journal model to the applications domain model.

    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 akka.persistence.PersistentActor. Use the specialised akka.persistence.journal.EventSeq#single method to emit exactly one event, or akka.persistence.journal.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.

    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
