[hibernate-issues] [Hibernate-JIRA] Closed: (HHH-3132) Event System With Phased Appraoch

Event System With Phased Appraoch --------------------------------- Key: HHH-3132 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3132 Project: Hibernate3 Issue Type: Improvement Components: core Affects Versions: 3.2.6 Environment: 3.x Reporter: Anirudh Vyas Assignee: Steve Ebersole Hibernate currently lacks proper event Delegation model; Granted it has a hook for listeners and iterates through them to find out which is appropriate or not. But a better way would be to add "Queuing of events" approach; meaning each event is first queued (for firing) and then Hibernate goes through cycles of phases (it can be internally thought of as a Phase 1 ---> Phase 2 ---> Phase 3 ). and each phase has a queue of events it has to process. A phase can have corresponding listener to process phases and clear the queue of events associated with it ( meaning events set to "fire" in the currently executing phase). All event creation should be centralized and all events should be queued through a factory. A flexible approach (ideally) would be to allow users to create Custom phases to enhance lifecycle of their own Application using Hibernate's Phase interface. "Phase implementation " could include usage of Enums, but its not mandatory ( so long as we are worried about back-wards compatibility). As it is, Hibernate Event system is poorly documented and not very well understood. What do you guys think ?
