      • randtag

        public static java.lang.Object randtag()
        Generates a random identifier object (with correct equals and hashCode semantics) that is unlikely to be equal to any other object generated by this method. This object can be used as a good unique actor message identifier.
        Returns:
        a newly allocated random identifier object

      • sendOrInterrupt

        public static void sendOrInterrupt​(ActorRef<?> actor,
                                   java.lang.Object message)
        Attempts to send a message to an actor, and if the message cannot be sent due to a full mailbox - interrupt the actor. This is useful for sending a shutdown message to possibly malfunctioning actors.
        Parameters:
        actor - the actor to which we send the message
        message - the message
