Detailed Description

Allows the application to attach arbitrary information to a Publisher or Subscriber.

The value of the GROUP_DATA is propagated and made available to applications through the built-in topics.

The group data is implemented as a vector of Bytes, and can be used to store any application defined data.

This QoS can be used by an application in combination with the DataReaderListener and DataWriterListener to implement conditional matching policies.
