    extends Actor
    INTERNAL API.

    LevelDB backed persistent mapping of String-based persistent actor ids to numeric ids.

    • Method Detail

      • allPersistenceIds

        scala.collection.immutable.Set<java.lang.String> allPersistenceIds()
      • idMap_$eq

        void idMap_$eq​(scala.collection.immutable.Map<java.lang.String,​java.lang.Object> x$1)
      • isNewPersistenceId

        boolean isNewPersistenceId​(java.lang.String id)
      • newPersistenceIdAdded

        void newPersistenceIdAdded​(java.lang.String id)
      • numericId

        int numericId​(java.lang.String id)
        Get the mapped numeric id for the specified persistent actor id. Creates and stores a new mapping if necessary.

        This method is thread safe and it is allowed to call it from a another thread than the actor's thread. That is necessary for Future composition, e.g. asyncReadHighestSequenceNr followed by asyncReplayMessages.

        Parameters:
        id - (undocumented)
        Returns:
        (undocumented)
      • preStart

        void preStart()
        Description copied from interface: Actor
        User overridable callback.

        Is called when an Actor is started. Actors are automatically started asynchronously when created. Empty default implementation.
        Specified by:

      • super$preStart

        void super$preStart()
        Get the mapped numeric id for the specified persistent actor id. Creates and stores a new mapping if necessary.

        This method is thread safe and it is allowed to call it from a another thread than the actor's thread. That is necessary for Future composition, e.g. asyncReadHighestSequenceNr followed by asyncReplayMessages.
