RemarksYou must define a class that implements this interface. You implement each of the callback methods for the interface so that they handle the received events according to the needs of your application.
Note: StreamLink queues events in the order they were raised and passes each event in turn to an appropriate callback method of the relevant listener. All listener callbacks execute in the same dedicated worker thread, so while a particular callback method is running no other callbacks will be invoked.
