Kaa: When onStarted() was called in main? - kaa

Question

Like to understand how onStarted() is being called. Does kaaClient.start() executed onStarted()? I tried to debug with ecplise and found it always executed "sleepForSeconds(MAX_SECONDS_TO_INIT_KAA);" before going to "LOG.info("--= Kaa client started =--")" but I can't tell when onStarted() was executed.
public static void main(String[] args) {
LOG.info("--= Data collection demo started =--");
/*
* Create a Kaa client with the Kaa desktop context.
*/
KaaClient kaaClient = Kaa.newClient(new DesktopKaaPlatformContext(), new SimpleKaaClientStateListener() {
#Override
public void onStarted() {
LOG.info("--= Kaa client started =--");
}
#Override
public void onStopped() {
LOG.info("--= Kaa client stopped =--");
}
}, true);
/*
* Set record count strategy for uploading every log record as soon as it is created.
*/
kaaClient.setLogUploadStrategy(new RecordCountLogUploadStrategy(LOGS_DEFAULT_THRESHOLD));
/*
* Displays endpoint's configuration and change sampling period each time configuration will be updated.
*/
kaaClient.addConfigurationListener(new ConfigurationListener() {
#Override
public void onConfigurationUpdate(Configuration configuration) {
LOG.info("--= Endpoint configuration was updated =--");
displayConfiguration(configuration);
Integer newSamplePeriod = configuration.getSamplePeriod();
if ((newSamplePeriod != null) && (newSamplePeriod > 0)) {
changeMeasurementPeriod(kaaClient, newSamplePeriod);
} else {
LOG.warn("Sample period value (= {}) in updated configuration is wrong, so ignore it.", newSamplePeriod);
}
}
});
/*
* Start the Kaa client and connect it to the Kaa server.
*/
kaaClient.start();
sleepForSeconds(MAX_SECONDS_TO_INIT_KAA);
/*
* Start periodical temperature value generating and sending results to Kaa node
*/
startMeasurement(kaaClient);
LOG.info("*** Press Enter to stop sending log records ***");
waitForAnyInput();
/*
* Stop generating and sending data to Kaa node
*/
stopMeasurement();
/*
* Stop the Kaa client and release all the resources which were in use.
*/
kaaClient.stop();
displayResults();
LOG.info("--= Data collection demo stopped =--");
}

Method onStarted() called in the start() method. For details see AbstaractKaaClient.
