Methods

	Name	Description
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	OnConnectionDeleted(DataReader)	Called when the connection object is cleaned up and the reconnect thread exits.
	OnConnectionDeleted(DataWriter)	Called when the publication connection object is cleaned up and the reconnect thread exits.
	OnDataAvailable	Handles the DataAvailableStatus communication status. The DataAvailableStatus indicates that samples are available on the DataReader. Applications receiving this status can use the various take and read operations on the DataReader to retrieve the data.
	OnDataOnReaders	Handles the DataOnReadersStatus communication status. The DataOnReadersStatus indicates that new data is available on some of the data readers associated with the subscriber. Applications receiving this status can call GetDataReaders on the subscriber to get the set of data readers with data available.
	OnInconsistentTopic	Handles the InconsistentTopicStatus communication status. The InconsistentTopicStatus indicates that a Topic was attempted to be registered that already exists with different characteristics. Typically, the existing Topic may have a different type associated with it.
	OnLivelinessChanged	Handles the LivelinessChangedStatus communication status. The LivelinessChangedStatus indicates that there have been liveliness changes for one or more DataWriters that are publishing instances for this DataReader.
	OnLivelinessLost	Handles the LivelinessLostStatus communication status. The LivelinessLostStatus indicates that the liveliness that the DataWriter committed through its Liveliness QoS has not been respected. This means that any connected DataReaders will consider this DataWriter no longer active
	OnOfferedDeadlineMissed	Handles the OfferedDeadlineMissedStatus communication status. The OfferedDeadlineMissedStatus indicates that the deadline offered by the DataWriter has been missed for one or more instances.
	OnOfferedIncompatibleQos	Handles the OfferedIncompatibleQosStatus communication status. The OfferedIncompatibleQosStatus indicates that an offered QoS was incompatible with the requested QoS of a DataReader.
	OnPublicationMatched	Handles the PublicationMatchedStatus communication status. The PublicationMatchedStatus indicates that the liveliness that the DataWriter committed through its Liveliness QoS has not been respected. This means that any connected DataReaders will consider this DataWriter no longer active.
	OnRequestedDeadlineMissed	Handles the RequestedDeadlineMissedStatus communication status. The RequestedDeadlineMissedStatus indicates that the deadline requested via the DeadlineQosPolicy was not respected for a specific instance.
	OnRequestedIncompatibleQos	Handles the RequestedIncompatibleQosStatus communication status. The RequestedIncompatibleQosStatus indicates that one or more QoS policy values that were requested were incompatible with what was offered.
	OnSampleLost	Handles the SampleLostStatus communication status. The SampleLostStatus indicates that a sample has been lost and never received by the DataReader.
	OnSampleRejected	Handles the SampleRejectedStatus communication status. The SampleRejectedStatus indicates that a sample received by the DataReader has been rejected.
	OnSubscriptionMatched	Handles the SubscriptionMatchedStatus communication status. The SubscriptionMatchedStatus indicates that either a compatible DataWriter has been matched or a previously matched DataWriter has ceased to be matched.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

The purpose of the DomainParticipantListener is to be the listener of last resort that is notified of all status changes not captured by more specific listeners attached to the Entity objects.When a relevant status change occurs, DDS will first attempt to notify the listener attached to the concerned Entity if one is installed. Otherwise, DDS will notify the Listener attached to the DomainParticipant.
