org.apache.hedwig.client.data.TopicSubscriber
Wrapper class object for the Topic + SubscriberId combination. Since the Subscribe flows always use the Topic + SubscriberId as the logical entity, we'll create a simple class to encapsulate that.
org.apache.stratos.messaging.broker.subscribe.TopicSubscriber
Any instance who needs to subscribe to a topic, should communicate with this object. @author nirmal
