Publisher and Subscriber Names
==============================

The information displayed in the different |AC| views depends on the
information that |AC| receives through Discovery. This information is primarily
related to the DomainParticipants, DataWriters and DataReaders.

To set the name of the Publisher, |AC| uses the DataWriterQos publication_name
field of the first DataWriter discovered for the Publisher.
(Although the Publisher’s PublisherQoS does have a publication_name field, that value isn’t sent over the wire.)
Similarly, |AC| uses the first discovered DataReader’s subscription_name as the name of the Subscriber.
