###
Companion object MqttServer

#### class MqttServer extends AnyRef

An MQTT server

You can accept incoming MQTT connection requests providing a io.vertx.scala.mqtt.MqttServer#endpointHandler. As the requests arrive, the handler will be called with an instance of io.vertx.scala.mqtt.MqttEndpoint in order to manage the communication with the remote MQTT client.

4.  def actualPort(): Int

   The actual port the server is listening on.

   The actual port the server is listening on. This is useful if you bound the server specifying 0 as port number signifying an ephemeral port

   Close the server supplying an handler that will be called when the server is actually closed (or has failed).

   Close the server supplying an handler that will be called when the server is actually closed (or has failed).

   completionHandler

     the handler called on completion

9.  def close(): Unit

   Close the server.

   Close the server.

   The close happens asynchronously and the server may not be closed until some time after the call has returned.

10.  def closeFuture(): Future[Unit]

    Like close but returns a scala.concurrent.Future instead of taking an AsyncResultHandler.

11.  def endpointHandler(handler: Handler[MqttEndpoint]): MqttServer

    Set the endpoint handler for the server.

    Set the endpoint handler for the server. If an MQTT client connect to the server a new MqttEndpoint instance will be created and passed to the handler

    handler

      the endpoint handler

    returns

      a reference to this, so the API can be used fluently
