Detailed Description

The SubscriberListener provides asynchronous notification of Subscriber events.

This listener can be installed during Subscriber creation, DomainParticipant_create_subscriber() as well as by calling Subscriber_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.

(

Subscriber *

[inline, virtual]

on_data_on_readers() is called when the CoreDX DDS middleware detects that data or data state information arrives at any DataReader contained within the Subscriber.

The status argument provides a snapshot of the status at the time the listener was invoked.
