Typedef Documentation

◆ OnConnectionCompletedHandler

using Aws::Crt::Mqtt::OnConnectionCompletedHandler = typedef std::function< void(MqttConnection &connection, int errorCode, ReturnCode returnCode, bool sessionPresent)>

Invoked when a connack message is received, or an error occurred.

◆ OnConnectionInterruptedHandler

using Aws::Crt::Mqtt::OnConnectionInterruptedHandler = typedef std::function<void(MqttConnection &connection, int error)>

Invoked Upon Connection loss.

◆ OnConnectionResumedHandler

using Aws::Crt::Mqtt::OnConnectionResumedHandler = typedef std::function<void(MqttConnection &connection, ReturnCode connectCode, bool sessionPresent)>

Invoked Upon Connection resumed.

◆ OnDisconnectHandler

using Aws::Crt::Mqtt::OnDisconnectHandler = typedef std::function<void(MqttConnection &connection)>

Invoked when a disconnect message has been sent.

◆ OnMultiSubAckHandler

using Aws::Crt::Mqtt::OnMultiSubAckHandler = typedef std::function<void( MqttConnection &connection, uint16_t packetId, const Vector<String> &topics, QOS qos, int errorCode)>

Invoked when a suback message for multiple topics is received.

◆ OnOperationCompleteHandler

using Aws::Crt::Mqtt::OnOperationCompleteHandler = typedef std::function<void(MqttConnection &connection, uint16_t packetId, int errorCode)>

◆ OnPublishReceivedHandler

using Aws::Crt::Mqtt::OnPublishReceivedHandler = typedef std::function<void(MqttConnection &connection, const String &topic, const ByteBuf &payload)>

Invoked upon receipt of a Publish message on a subscribed topic.

◆ OnSubAckHandler

using Aws::Crt::Mqtt::OnSubAckHandler = typedef std::function< void(MqttConnection &connection, uint16_t packetId, const String &topic, QOS qos, int errorCode)>

Invoked when a suback message is received.

◆ OnWebSocketHandshakeIntercept

using Aws::Crt::Mqtt::OnWebSocketHandshakeIntercept = typedef std::function< void(std::shared_ptr<Http::HttpRequest> req, const OnWebSocketHandshakeInterceptComplete &onComplete)>

Invoked during websocket handshake to give users opportunity to transform an http request for purposes such as signing/authorization etc... Returning from this function does not continue the websocket handshake since some work flows may be asynchronous. To accommodate that, onComplete must be invoked upon completion of the signing process.

◆ OnWebSocketHandshakeInterceptComplete

using Aws::Crt::Mqtt::OnWebSocketHandshakeInterceptComplete = typedef std::function<void(const std::shared_ptr<Http::HttpRequest> &, int errorCode)>

Callback for users to invoke upon completion of, presumably asynchronous, OnWebSocketHandshakeIntercept callback's initiated process.

◆ QOS

using Aws::Crt::Mqtt::QOS = typedef aws_mqtt_qos

◆ ReturnCode

using Aws::Crt::Mqtt::ReturnCode = typedef aws_mqtt_connect_return_code
