public class MessageConsumer<T> extends Object implements ReadStream<Message<T>>
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.rxjava.core.eventbus.Message<T>>)
method is invoked.
The consumer is unregistered from the event bus using the unregister()
method or by calling the
handler(io.vertx.core.Handler<io.vertx.rxjava.core.eventbus.Message<T>>)
with a null value..
