Example 1 with GetPendingJobExecutionsResponse

use of software.amazon.awssdk.iot.iotjobs.model.GetPendingJobExecutionsResponse in project aws-iot-device-sdk-java-v2 by aws.

the class IotJobsClient method SubscribeToGetPendingJobExecutionsAccepted.

/**
 * Subscribes to the accepted topic for the GetPendingJobsExecutions operation
 *
 * Once subscribed, `handler` is invoked each time a message matching
 * the `topic` is received. It is possible for such messages to arrive before
 * the SUBACK is received.
 *
 * AWS documentation: https://docs.aws.amazon.com/iot/latest/developerguide/jobs-api.html#mqtt-getpendingjobexecutions
 *
 * @param request Subscription request configuration
 * @param qos Maximum requested QoS that server may use when sending messages to the client.
 *            The server may grant a lower QoS in the SUBACK
 * @param handler callback function to invoke with messages received on the subscription topic
 * @param exceptionHandler callback function to invoke if an exception occurred deserializing a message
 *
 * @return a future containing the MQTT packet id used to perform the subscribe operation
