3.3.2. PublisherListener

PublisherListener is an abstract class defining the callbacks that will be triggered in response to state changes on the Publisher. By default, all these callbacks are empty and do nothing. The user should implement a specialization of this class overriding the callbacks that are needed on the application. Callbacks that are not overridden will maintain their empty implementation.

PublisherListener inherits from DataWriterListener. Therefore, it has the ability to react to all events that are reported to the DataWriter. Since events are always notified to the most specific Entity Listener that can handle the event, callbacks that PublisherListener inherits from DataWriterListener will only be called if the triggering DataWriter has no Listener attached, or if the callback is disabled by the StatusMask on the DataWriter.

PublisherListener does not add any new callback. Please, refer to the DataWriterListener for the list of inherited callbacks and override examples.
