 /**
  * This class can be used to create a unique service and redirect calls
  * to this service similarly to KDBusService(KDBusService::Unique).
  * @code
  *   YourApplication app(argc, argv);
  *
  *   KUniqueService service;
  *   QObject::connect(&service, &KUniqueService::activateRequested,
  *                    &app, &YourApplication::slotActivateRequested);
  *   QObject::connect(&app, &YourApplication::setExitValue,
  *   &service, [&service](int i) {
  *       service.setExitValue(i);
  *   });
  * @endcode
  * This will redirect calls to running instances over the
  * the slotActivateRequested. When you set the exit
  * value the calling process will afterwards exit with the
  * code provided.
  * If you do not set the exit value the application will not
  * be terminated.
