This QosPolicy allows the application to attach additional information to a Topic Entity. This information is distributed with the BuiltinTopics.
| Value | Meaning | Concerns | RxO | Changeable |
|---|---|---|---|---|
| A sequence of octets: value | A sequence of octets that holds the application topic data. By default, the sequence has length 0. | Topic | No | Yes |
The purpose of this QoS is to allow 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.
