[Hibernate-issues] [Hibernate-JIRA] Updated: (HHH-1696) add outer join support for aliases on detached cirteria

Benoit Goudreault-Emond updated HHH-1696:
-----------------------------------------

    Attachment: HHH-1696.patch

I've attached a simple patch against 3.1.3 that implements this feature.  Actually, what the patch does is implement relevant functions in Criteria in the DetachedCriteria class.  Those are:

- All variants of createAlias()
- All variants of createCriteria()
- All variants of setLockMode()
- setComment() (not used much, I suppose, but why not?)

It wasn't clear whether setFlushMode() and setCacheMode() should be applied to DetachedCriteria.  My guess is that those are more properties of the executable criteria, like setFirstResult()/setMaxResult(), and aren't part of the query itself, but rather, of the execution environment.

> Recently, support for aliasing via an outer join was added to the Criteria class.  The method
> createAlias(String associationPath, String alias, int joinType) 
> , however, is not defined for DetachedCriteria.  Adding this functionality would be extremely helpful for applications that expose detached criteria as their query api, and also for subqueries.
