Detailed Description

The purpose of this QoS is to allow the application to attach additional information to the created Publisher or Subscriber.

The value of the GROUP_DATA is available to the application on the DataReader and DataWriter entities and is propagated by means of the built-in topics. This QoS can be used by an application combination with the DataReaderListener and DataWriterListener to implement matching policies similar to those of the PARTITION QoS except the decision can be made based on an application-defined policy.
