Examples of org.xmlBlaster.engine.qos.SubscribeQosServer

org.xmlBlaster.engine.qos.SubscribeQosServer
Handling of subscribe() quality of services in the server core.
This decorator hides the real qos data object and gives us a server specific view on it.

QoS Informations sent from the client to the server via the subscribe() method
They are needed to control xmlBlaster

For the xml representation see QueryQosSaxFactory.
