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.)
	OnBudgetExceeded	Allow reporting delays in excess of the policy duration setting.
	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.
	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.
	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.
	OnSubscriptionDisconnected	Called when a subscription connection failure has been detected and there are still associations using the connection after the configurable graceful_disconnected_period.
	OnSubscriptionLost	Called when a subscription connection is lost and hence one or more associations from this publication to some subscribers have been lost. A connection is "lost" when the retry attempts have been exhausted.
	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.
	OnSubscriptionReconnected	Called when a disconnected subscription connection has been reconnected.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
