Detailed Description

Class that contains information about available DataWriters within the system.

The DCPSPublication topic communicates the existence of datawriters by means of the PublicationBuiltinTopicData datatype. Each PublicationBuiltinTopicData sample in a Domain represents a datawriter in that Domain: a new PublicationBuiltinTopicData instance is created when a newly-added DataWriter is enabled, and it is disposed when that DataWriter is deleted. An updated PublicationBuiltinTopicData sample is written each time the DataWriter (or the Publisher to which it belongs) modifies a QosPolicy that applies to the entities connected to it. Also will it be updated when the writer looses or regains its liveliness.

/* 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 DCPSPublication builtin reader. */
PublicationBuiltinTopicDataDataReader builtinReader =
    (PublicationBuiltinTopicDataDataReader)builtinSubscriber.LookupDataReader("DCPSPublication");

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