Detailed Description

The DataReaderListener provides asynchronous notification of DataReader events.

This listener can be installed during DataReader creation, Subscriber.create_datareader(), as well as by calling DataReader.set_listener().

Note

The listener callback methods should be lightweight and should not block. If a callback method blocks, it will block all other callback operations within the same DomainParticipant.
