[Feature] Utility class used for creating Actor.

[Roiocam]

Motivation

In typed actor, if we want to create an actor, we have to use code like this:

  CompletionStage<ActorRef<MyType>> future =  AskPattern.<SpawnProtocol.Command, ActorRef<MyType>>ask(
                                system,
                                reply ->
                                        new SpawnProtocol.Spawn<>(
                                                MyType.createBehavior(),
                                                "name",
                                                Props.empty(),
                                                reply),
                                Duration.ofSeconds(3),
                                system.scheduler())

ActorRef<MyType> actorRef = future.toCompletableFuture().join();

for comparison, in classic we have:

Props props = Props.create(MyType.class, ()-> new MyType()).withDispatcher("dispatcher");
ActorRef actorRef = actorSystem.actorOf(props, "name");

Can we wrapper those ask into utility class like this?

  public interface SpawnUtility {

        <T> ActorRef<T> spawn(ActorSystem<SpawnProtocol.Command> spawnableSystem, Behavior<T> behavior, String name, Props props);

        <T> ActorRef<T> spawn(ActorSystem<SpawnProtocol.Command> spawnableSystem, Behavior<T> behavior, String name);

        <T> ActorRef<T> spawn(ActorSystem<SpawnProtocol.Command> spawnableSystem, Behavior<T> behavior);

        <T> CompletionStage<ActorRef<T>> spawnAsync(ActorSystem<SpawnProtocol.Command> spawnableSystem, Behavior<T> behavior, String name, Props props);

        <T> CompletionStage<ActorRef<T>> spawnAsync(ActorSystem<SpawnProtocol.Command> spawnableSystem, Behavior<T> behavior, String name);

        <T> CompletionStage<ActorRef<T>> spawnAsync(ActorSystem<SpawnProtocol.Command> spawnableSystem, Behavior<T> behavior);

    }

    @Test
    public void spawnTest(){
        ActorSystem<SpawnProtocol.Command> spawnableSystem = null;
        SpawnUtility utility = null;

        ActorRef<MyType> actorRef = utility.spawn(spawnableSystem, MyType.createBehavior(), "name");
        actorRef.tell(null);
    }
