Package com.polarion.platform.persistence.events

Interface IPersistenceEvent

public interface IPersistenceEvent
The persistence event groups the information on objects, which were changed together (i.e. during one commit).

The event might contain one or more objects, empty events are not passed.

Depending on the storage support, the getRevision() and getPreviousRevision() methods return null or useful value. If they return null, then it is likely that the storage has no way of grouping events and in such a case only a single object is likely to be contained in the event.
