# MqttClient

`open class MqttClient`

An MQTT client NOTE: This class has been automatically generated from the io.vertx.mqtt.MqttClient non RX-ified interface using Vert.x codegen.

### Constructors

<init> | `MqttClient(delegate: MqttClient)`

### Properties

__TYPE_ARG | `static val __TYPE_ARG: TypeArg<MqttClient>`

### Functions

clientId | `open fun clientId(): String`
closeHandler | `open fun closeHandler(closeHandler: Handler<Void>): MqttClient` Set a handler that will be called when the connection with server is closed
connect | `open fun connect(port: Int, host: String, connectHandler: Handler<AsyncResult<MqttConnAckMessage>>): MqttClient` `open fun connect(port: Int, host: String, serverName: String, connectHandler: Handler<AsyncResult<MqttConnAckMessage>>): MqttClient` Connects to an MQTT server calling connectHandler after connection
create | `open static fun create(vertx: Vertx, options: MqttClientOptions): MqttClient` Return an MQTT client instance `open static fun create(vertx: Vertx): MqttClient` Return an MQTT client instance using the default options
disconnect | `open fun disconnect(): MqttClient` Disconnects from the MQTT server `open fun disconnect(disconnectHandler: Handler<AsyncResult<Void>>): MqttClient` Disconnects from the MQTT server calling disconnectHandler after disconnection
equals | `open fun equals(other: Any?): Boolean`
exceptionHandler | `open fun exceptionHandler(handler: Handler<Throwable>): MqttClient` Set an exception handler for the client, that will be called when an error happens in internal netty structures. `io.netty.handler.codec.DecoderException` can be one of the cause
getDelegate | `open fun getDelegate(): MqttClient`
hashCode | `open fun hashCode(): Int`
isConnected | `open fun isConnected(): Boolean`
newInstance | `open static fun newInstance(arg: MqttClient): MqttClient`
ping | `open fun ping(): MqttClient` This method is needed by the client in order to avoid server closes the connection due to the keep alive timeout if client has no messages to send
pingResponseHandler | `open fun pingResponseHandler(pingResponseHandler: Handler<Void>): MqttClient` Sets handler which will be called after PINGRESP packet receiving
publish | `open fun publish(topic: String, payload: Buffer, qosLevel: MqttQoS, isDup: Boolean, isRetain: Boolean): MqttClient` `open fun publish(topic: String, payload: Buffer, qosLevel: MqttQoS, isDup: Boolean, isRetain: Boolean, publishSentHandler: Handler<AsyncResult<Int>>): MqttClient` Sends the PUBLISH message to the remote MQTT server
publishCompletionHandler | `open fun publishCompletionHandler(publishCompletionHandler: Handler<Int>): MqttClient` Sets handler which will be called each time publish is completed
publishHandler | `open fun publishHandler(publishHandler: Handler<MqttPublishMessage>): MqttClient` Sets handler which will be called each time server publish something to client
rxConnect | `open fun rxConnect(port: Int, host: String): Single<MqttConnAckMessage>` `open fun rxConnect(port: Int, host: String, serverName: String): Single<MqttConnAckMessage>` Connects to an MQTT server calling connectHandler after connection
rxDisconnect | `open fun rxDisconnect(): Single<Void>` Disconnects from the MQTT server calling disconnectHandler after disconnection
rxPublish | `open fun rxPublish(topic: String, payload: Buffer, qosLevel: MqttQoS, isDup: Boolean, isRetain: Boolean): Single<Int>` Sends the PUBLISH message to the remote MQTT server
rxSubscribe | `open fun rxSubscribe(topic: String, qos: Int): Single<Int>` Subscribes to the topic with a specified QoS level `open fun rxSubscribe(topics: MutableMap<String, Int>): Single<Int>` Subscribes to the topic and adds a handler which will be called after the request is sent
rxUnsubscribe | `open fun rxUnsubscribe(topic: String): Single<Int>` Unsubscribe from receiving messages on given topic
subscribe | `open fun subscribe(topic: String, qos: Int): MqttClient` `open fun subscribe(topic: String, qos: Int, subscribeSentHandler: Handler<AsyncResult<Int>>): MqttClient` Subscribes to the topic with a specified QoS level `open fun subscribe(topics: MutableMap<String, Int>): MqttClient` Subscribes to the topics with related QoS levels `open fun subscribe(topics: MutableMap<String, Int>, subscribeSentHandler: Handler<AsyncResult<Int>>): MqttClient` Subscribes to the topic and adds a handler which will be called after the request is sent
subscribeCompletionHandler | `open fun subscribeCompletionHandler(subscribeCompletionHandler: Handler<MqttSubAckMessage>): MqttClient` Sets handler which will be called after SUBACK packet receiving
toString | `open fun toString(): String`
unsubscribe | `open fun unsubscribe(topic: String): MqttClient` `open fun unsubscribe(topic: String, unsubscribeSentHandler: Handler<AsyncResult<Int>>): MqttClient` Unsubscribe from receiving messages on given topic
unsubscribeCompletionHandler | `open fun unsubscribeCompletionHandler(unsubscribeCompletionHandler: Handler<Int>): MqttClient` Sets handler which will be called after UNSUBACK packet receiving
