1. case class ConnOptions(username: String = null, password: String = null, cleanSession: Boolean = CLEAN_SESSION_DEFAULT, maxInflight: Int = MAX_INFLIGHT_DEFAULT * 10, will: Publish = null) extends Product with Serializable

   

   Convenient class to generate MqttConnectOptions

   Convenient class to generate MqttConnectOptions

   username

   nullable

   password

   nullable

   cleanSession

   Sets whether the client and server should remember state across restarts and reconnects

   maxInflight

   The max inflight limits to how many messages we can send without receiving acknowledgments. Default is MAX_INFLIGHT_DEFAULT * 10

   will

   A last will and testament message (and topic, and qos) that will be set on the connection

2. class Message extends AnyRef

   

3. class MqttPubSub extends FSM[PSState, Unit]

   

   Notes: 1.

   Notes: 1. MqttClientPersistence will be set to null. @see org.eclipse.paho.client.mqttv3.MqttMessage#setQos(int) 2. MQTT client will auto-reconnect

4. case class PSConfig(brokerUrl: String, _clientId: String = null, conOpt: MqttConnectOptions = ConnOptions().get, stashTimeToLive: Duration = 1.minute, stashCapacity: Int = 8000, reconnectDelayMin: FiniteDuration = 10.millis, reconnectDelayMax: FiniteDuration = 30.seconds) extends Product with Serializable

   
   brokerUrl

   ex tcp://test.mosquitto.org:1883

   _clientId

   MqttAsyncClient id. If left null, the code falls back to a generated ID.

   stashTimeToLive

   messages received when disconnected will be stash. Messages isOverdue after stashTimeToLive will be discard. See also stashCapacity

   stashCapacity

   pubSubStash will be drop first haft elems when reach this size

   reconnectDelayMin

   when received Disconnected event, we will first delay reconnectDelayMin to try Connect. + if connect success => we reinit connectCount + else => ConnListener.onFailure will send Disconnected to this FSM => we re-schedule Connect with

   delay = reconnectDelayMin * 2^connectCount

   reconnectDelayMax

   max delay to retry connecting

5. sealed trait PSState extends AnyRef

   

6. class Publish extends AnyRef

   

   This class wrap params for publishing to mqtt.

   This class wrap params for publishing to mqtt.

   Send an instance of this class to the MqttPubSub actor for publishing:

   pubsub ! Publish("some_topic", "12345".getBytes

7. case class Subscribe(topic: String, ref: ActorRef, qos: Int = 0) extends Product with Serializable

   

   TODO support wildcards subscription TODO support Unsubscribe

8. case class SubscribeAck(subscribe: Subscribe, fail: Option[Throwable]) extends Product with Serializable
