Return to DDS Quality of Service
The TOPIC_DATA
QoS allows the application to attach additional information to the created Topic such that when a
remote application discovers their existence it can examine the information and use it in an application-defined way. In combination with the listeners on the DataReader
and DataWriter
as well as by means of operations such as ignore_topic, these QoS can assist an application to extend the provided QoS.
