Detailed Description

The PublisherListener provides asynchronous notification of Publisher events. This listener can be installed during Publisher creation DomainParticipant_create_publisher(), as well as by calling Publisher_set_listener().

Member Function Documentation

long get_nil_mask

(

)

get_nil_mask() returns a bitmask indicating which listener methods (if any) should be considered NIL, and therefore, should not be invoked.

void on_liveliness_lost	(	DataWriter	writer,
		LivelinessLostStatus	status
	)

Called when the CoreDX DDS middleware detects that a DataWriter contained in the Publisher has not satisfied its LIVELINESS QoS setting. This listener is invoked only if the concerned DataWriter does not have an on_offered_deadline_missed listener installed.

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

void on_offered_deadline_missed	(	DataWriter	writer,
		OfferedDeadlineMissedStatus	status
	)

Called when the CoreDX DDS middleware detects that a DataWriter contained in the Publisher has failed to meet its DEADLINE QoS commitment. This listener is invoked only if the concerned DataWriter does not have an on_offered_deadline_missed listener installed.

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

void on_offered_incompatible_qos	(	DataWriter	writer,
		OfferedIncompatibleQosStatus	status
	)

Called when the CoreDX DDS middleware detects that a DataWriter contained in the Publisher has offered a QoS policy setting that is incompatible with that requested by a potentially matching DataReader. This listener is invoked only if the concerned DataWriter does not have an on_offered_deadline_missed listener installed.

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

void on_publication_matched	(	DataWriter	writer,
		PublicationMatchedStatus	status
	)

Called when the CoreDX DDS middleware detects that a DataWriter contained in the Publisher has matched with a DataReader or has ceased to be matched with a DataReader. This listener is invoked only if the concerned DataWriter does not have an on_offered_deadline_missed listener installed.

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