Package: DDS.TopicBuiltinTopicData_DataReader

Description

package DDS.TopicBuiltinTopicData_DataReader is

Summary: Instantiates DataReader < DDS.TopicBuiltinTopicData > .

DDS.DataReader of topic DDS.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.
