Examples of org.hibernate.engine.ActionQueue

org.hibernate.engine.ActionQueue
Responsible for maintaining the queue of actions related to events.
The ActionQueue holds the DML operations queued as part of a session's transactional-write-behind semantics. DML operations are queued here until a flush forces them to be executed against the database. @author Steve Ebersole
