Which message communication pattern is used in generated Vertx Service Proxy classes?

can somebody please clarify which type of message communication patterns:

1. Point-To-Point
2. Request-Reply
3. Publish/Subscribe ... is used in GENERATED Vert.X Service Proxy classes for RESTful CRUD app (which has 4 HttpServerVerticles which communicates with DatabaseVerticle and those are deployed by MainVerticle)? Thank you in advance.

I persume it's Request-Reply since it sends Http Request and recieves Http Response since in "Vert.x in action" it states (in Chapter 3.1.4):

If you need message consumers to get back to the entity that sent the event then go for request-reply. 

Any help/advice is greatly appreciated.
