Detailed Description

The TopicListener provides asynchronous notification of Topic events.

This listener can be installed during Topic creation (DomainParticipant_create_topic() and related) as well as by calling Topic_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.

virtual void DDS::TopicListener::on_inconsistent_topic	(	Topic *	,
		InconsistentTopicStatus
	)			`[inline, virtual]`

on_inconsistent_topic() is called when the CoreDX DDS middleware detects that another topic exists with different (inconsistent) characteristics.

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