Class Message<T>

java.lang.Object
io.vertx.rxjava3.core.eventbus.Message<T>
All Implemented Interfaces:
io.vertx.lang.rx.RxDelegate

public class Message<T> extends Object implements io.vertx.lang.rx.RxDelegate
Represents a message that is received from the event bus in a handler.

Messages have a body(), which can be null, and also headers(), which can be empty.

If the message was sent specifying a reply handler, it can be replied to using reply(Object).

If you want to notify the sender that processing failed, then fail(int, String) can be called.

NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.
