class MessageConsumer[T] extends ReadStream[Message[T]]

An event bus consumer object representing a stream of message to an io.vertx.scala.core.eventbus.EventBus address that can be read from.

The io.vertx.scala.core.eventbus.EventBus#consumer or io.vertx.scala.core.eventbus.EventBus#localConsumer creates a new consumer, the returned consumer is not yet registered against the event bus. Registration is effective after the io.vertx.scala.core.eventbus.MessageConsumer#handler method is invoked.

The consumer is unregistered from the event bus using the io.vertx.scala.core.eventbus.MessageConsumer#unregister method or by calling the io.vertx.scala.core.eventbus.MessageConsumer#handler with a null value..
