      • connect

        @CheckReturnValue
public io.smallrye.mutiny.Uni<MqttConnAckMessage> connect​(int port,
                                                          String host)
        Connects to an MQTT server calling connectHandler after connection

        Unlike the bare Vert.x variant, this method returns a Uni. Don't forget to subscribe on it to trigger the operation.

        Parameters:
        port - port of the MQTT server
        host - hostname/ip address of the MQTT server
        Returns:
        the uni firing the result of the operation when completed, or a failure if the operation failed.

      • connectAndAwait

        public MqttConnAckMessage connectAndAwait​(int port,
                                          String host)
        Blocking variant of connect(int,String).

        This method waits for the completion of the underlying asynchronous operation. If the operation completes successfully, the result is returned, otherwise the failure is thrown (potentially wrapped in a RuntimeException).

        Parameters:
        port - port of the MQTT server
        host - hostname/ip address of the MQTT server
        Returns:
        the MqttConnAckMessage instance produced by the operation.

        public MqttClient connectAndForget​(int port,
                                   String host)
        Variant of connect(int,String) that ignores the result of the operation.

        This method subscribes on the result of connect(int,String), but discards the outcome (item or failure). This method is useful to trigger the asynchronous operation from connect(int,String) but you don't need to compose it with other operations.

        Parameters:
        port - port of the MQTT server
        host - hostname/ip address of the MQTT server
        Returns:
        the instance of MqttClient to chain method calls.
