# Message 

###
Companion object Message

#### class Message[T] extends AnyRef

Represents a message that is received from the event bus in a handler.

Messages have a io.vertx.scala.core.eventbus.Message#body, which can be null, and also io.vertx.scala.core.eventbus.Message#headers, which can be empty.

If the message was sent specifying a reply handler it will also have a io.vertx.scala.core.eventbus.Message#replyAddress. In that case the message can be replied to using that reply address, or, more simply by just using io.vertx.scala.core.eventbus.Message#reply.

If you want to notify the sender that processing failed, then io.vertx.scala.core.eventbus.Message#fail can be called.
