How to do std::move() in vertx

[dekst]

I have multiple WebServer verticles to share one DbService verticle in a Vertx instance.

How can I pass data to be saved to DB to DbService?

The DbClient is an expensive resource, hence cannot be created with each WebServer instance.

1. EventBus:  I think this is for small size messages.

2. LocalMap:  Does it support JsonObject OR I need to use Json.encode() to encode to string and decode it in DbService?

3. In the main class create a shared version DbClient, and pass it to WebServer constructor?

Which one is the right way?

Do we have anything like std::move() in vertx?

public class WebServer extends AbstractVerticle {

    @Override

    public void start() {

        final Router app = Router.router(vertx);

        app.route().handler(BodyHandler.create());

        app.post(RESOURCE_PATH + "/*").handler(new PostHandler());

        vertx.createHttpServer()

            .requestHandler(app::accept)

            .listen(8080, handler -> {

                if (handler.succeeded()) {

                    Log.d(LOG_TAG, "http://localhost:8080/");

                } else {

                    Log.d(LOG_TAG, "Failed to listen on port 8080");

                }

            });

    }

}

public class DbService extends AbstractVerticle {

      DbClient mDbClient = DbClient.create();

}

Thanks!
