Detailed Description

The DataWriterListener provides asynchronous notification of DataWriter events.

This listener can be installed during DataWriter creation, Publisher_create_datawriter(), as well as by calling DataWriter_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.

Member Function Documentation

virtual void DDS::DataWriterListener::on_liveliness_lost	(	DataWriter *	,
		LivelinessLostStatus
	)			[inline, virtual]

on_liveliness_lost() is called when the CoreDX DDS middleware detects that the DataWriter has not satisfied its LIVELINESS QoS setting.

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

virtual void DDS::DataWriterListener::on_offered_deadline_missed	(	DataWriter *	,
		OfferedDeadlineMissedStatus
	)			[inline, virtual]

on_offered_deadline_missed() is called when the CoreDX DDS middleware detects that the deadline that the DataWriter has offered Through the DEADLINE QoS was not satisfied. That is, the DataWriter has failed to update an instance with the frequency specified in the DEADLINE QoS.

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

virtual void DDS::DataWriterListener::on_offered_incompatible_qos	(	DataWriter *	,
		OfferedIncompatibleQosStatus
	)			[inline, virtual]

on_offered_incompatible_qos() is called when the CoreDX DDS middleware detects that the DataWriter has offered a QoS policy setting that is incompatible with that requested by a potentially matching DataReader.

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

virtual void DDS::DataWriterListener::on_publication_matched	(	DataWriter *	,
		PublicationMatchedStatus
	)			[inline, virtual]

on_publication_matched() is called when the CoreDX DDS middleware detects that the DataWriter has matched with a DataReader or has ceased to be matched with a DataReader.

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