Detailed Description

Allows the application to attach arbitrary information to a DomainParticipant, DataWriter or DataReader QoS.

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

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