/**
* A Vert.x event-bus is a light-weight distributed messaging system which allows different parts of your application,
* or different applications and services to communicate with each in a loosely coupled way.
*
* An event-bus supports publish-subscribe messaging, point-to-point messaging and request-response messaging.
*
* Message delivery is best-effort and messages can be lost if failure of all or part of the event bus occurs.
*
* Please refer to the documentation for more information on the event bus.
*
*
* NOTE: This class has been automatically generated from the {@link io.vertx.core.eventbus.EventBus original} non RX-ified interface using Vert.x codegen.
