[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-4629) Add Criteria API to check collections for particular members

Add Criteria API to check collections for particular members ------------------------------------------------------------ Key: HHH-4629 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4629 Project: Hibernate Core Issue Type: Patch Components: core Affects Versions: 3.5 Reporter: Chris Wilson Attachments: hibernate-collection-contains.patch, hibernate-collection-contains.patch, hibernate-collection-contains.patch Original Estimate: 15 minutes Remaining Estimate: 15 minutes Very few Criteria Restrictions apply to a collection. Currently as far as I can tell the only relevant ones are Restrictions.isEmpty() and isNotEmpty(). It's pretty useful to be able to check for a collection containing a particular value (object), like this: org = session.createCriteria(Org.class); org.add(Restrictions.contains("projects", project2)); assertEquals(Arrays.asList(new Org[]{org1, org2}), org.list()); The attached patch implements this.
