Is there a name for this asyncronous actor initialization pattern?

Whenever I create an actor that needs some asynchronously obtained data to initialize itself, I find myself using a pattern like this. Does it have a name? (And is it the best way to do it?)

class AsyncInitActor(db: Database, someId: UUID) extends Actor with ActorStash {
    case class Initialize(something: Something)

    override def preStart() = {
        db.getSomething(someId) onSuccess { something =>
            self ! Initialize(something)
        }
    }

    def receive = {
        case Initialize(something) =>
            context become initialized(something)
            unstashAll()

        case _ => stash()
    }

    def initialized(something): Receive = {
        case whatever =>
    }
}

In the case of actors created by cluster sharding, the asynchronous request happens in receive instead of preStart.
