public interface SubscriptionIterator
The SubscriptionIterator
provides serial access to subscription.
It follows the same pattern as DataIterator
except it does not go
through data fields.
NOTE: This interface is formally unrelated to its data analogue to enforce strict type safety; also their state diagrams are not compatible.
