Message (Vert.x Stack - Docs 3.9.3 API)

java.lang.Object
- io.vertx.reactivex.core.eventbus.Message<T>

```
public class Message<T>
extends Object
```
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(java.lang.Object).
If you want to notify the sender that processing failed, then fail(int, java.lang.String) can be called.
NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.
