- io.vertx.reactivex.core.eventbus.MessageConsumer<T>

All Implemented Interfaces:

ReadStream<Message<T>>, StreamBase
```
public class MessageConsumer<T>
extends Object
implements ReadStream<Message<T>>
```
An event bus consumer object representing a stream of message to an EventBus address that can be read from.
The EventBus.consumer(java.lang.String) or EventBus.localConsumer(java.lang.String) creates a new consumer, the returned consumer is not yet registered against the event bus. Registration is effective after the handler(io.vertx.core.Handler<io.vertx.reactivex.core.eventbus.Message<T>>) method is invoked.
The consumer is unregistered from the event bus using the unregister(io.vertx.core.Handler<io.vertx.core.AsyncResult<java.lang.Void>>) method or by calling the handler(io.vertx.core.Handler<io.vertx.reactivex.core.eventbus.Message<T>>) with a null value..
NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.
