Subject [jira] Created: (OPENJPA-1288) Support alias() on Criteria Query API
Date Tue, 08 Sep 2009 15:53:57 GMT
Support alias() on Criteria Query API
-------------------------------------

                 Key: OPENJPA-1288
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1288
             Project: OpenJPA
          Issue Type: New Feature
          Components: jpa, query
    Affects Versions: 2.0.0-M3, 2.0.0-M4, 2.0.0
            Reporter: Pinaki Poddar
            Assignee: Pinaki Poddar
             Fix For: 2.0.0-M3, 2.0.0-M4, 2.0.0


Selection.alias() according to latest JPA 2.0 creates new instances rather than adding an
alias name to the receiver.
This apparently simple change can have a relatively large impact, because we maintain Selection
terms keyed by its alias.
If we go for a delegation pattern to implement alias(), then all Selection derivations (quite
a few of them) are to be delegated. 

Comments/thoughts?
