There are 3 ways to use this class:

• Unicast - Use a specific DOFObjectID to subscribe to just one provider. The subscribe operation is not flooded. Interest is required because this case uses an internal query to find the provider.
• Multicast - Use DOFObjectID.BROADCAST to subscribe to all providers of the specified DOFInterface . The subscribe operation is flooded. Interest is not required because no internal query is used.
• Query - Use a DOFQuery to specify what to subscribe to. Only one subscription is maintained at a time.
