[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-1046) Make Criteria & DetachedCriteria cloneable

Make Criteria & DetachedCriteria cloneable ------------------------------------------ Key: HHH-1046 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1046 Project: Hibernate3 Type: Improvement

Components: core Versions: 3.0.5 Environment: Hibernate 3.0.5, Database irrelevant Reporter: Corey Puffalt Priority: Minor

Criteria and in particular, DetachedCriteria would be substantially more useful if they were made cloneable either by implementing clone() or via some other method if Cloneable is abhorrent. This has already come up a number of times on the forums where people want to do things like write general methods that can take a Criteria and perform a count on it. However, doing so has sideaffects (you've changed the Projection on the Criteria.) Some of these sideaffects are reversable but requires extra care and attention. Furthermore, not all operations are reversable. For instance, addOrder() etc. In my opinion, it would greatly enhance the utility of these classes by providing this feature.
