Detailed Description

Class that contains information about available DataReaders within the system.

The DCPSSubscription topic communicates the existence of datareaders by means of the SubscriptionBuiltinTopicData datatype. Each SubscriptionBuiltinTopicData sample in a Domain represents a datareader in that Domain: a new SubscriptionBuiltinTopicData instance is created when a newly-added DataReader is enabled, and it is disposed when that DataReader is deleted. An updated SubscriptionBuiltinTopicData sample is written each time the DataReader (or the Subscriber to which it belongs) modifies a QosPolicy that applies to the entities connected to it.

/* Defaults are used and possible errors are ignored. */

/* Get builtin subscriber. */
DDS.DomainParticipantFactory factory = DDS.DomainParticipantFactory.Instance;
DDS.IDomainParticipant participant = factory.CreateParticipant(DDS.DomainId.Default);
DDS.ISubscriber builtinSubscriber = participant.BuiltInSubscriber;

/* Get DCPSSubscription builtin reader. */
SubscriptionBuiltinTopicDataDataReader builtinReader =
    (SubscriptionBuiltinTopicDataDataReader)builtinSubscriber.LookupDataReader("DCPSSubscription");

/* The builtinReader can now be used just as a normal typed DataReader (like Space.FooDataReader)
 * to get DDS.SubscriptionBuiltinTopicData samples. */
