Detailed Description

Instantiates DataReader < DDS::TopicBuiltinTopicData > .

DDS::DataReader of topic DDS::TopicBuiltinTopicDataTypeSupport::TOPIC_TOPIC_NAME used for accessing DDS::TopicBuiltinTopicData of the remote DDS::Topic.

Note: The DDS::TopicBuiltinTopicData built-in topic is meant to convey information about discovered Topics. This Topic's samples are not propagated in a separate packet on the wire. Instead, the data is sent as part of the information carried by other built-in topics (DDS::PublicationBuiltinTopicData and DDS::SubscriptionBuiltinTopicData). Therefore TopicBuiltinTopicData DataReaders will not receive any data.
