Benjamin Lerman commented on HIB-219: ------------------------------------- Forgot to say: Patch is against 3.3 version. > Handle bidirectional associations. > ---------------------------------- > > Key: HIB-219 > URL: http://jira.andromda.org/browse/HIB-219 > Project: Hibernate Cartridge > Type: New Feature > Versions: 3.0M3, 3.0RC1, 3.0 RC2, 3.0 Final, 3.0.1, 3.1M1, 3.1-RC1, 3.1, > 3.2-RC1 > Reporter: Benjamin Lerman > Assignee: Carlos Cuenca > Attachments: HibernateMetafacadeModel.xml.zip, hibernate-patch > > The hibernate cartridge do not take into account if an association is > bidirectional when it does generate the getter setter for the association. > That means it is of the responsibility of the user to synchronize the two > end of the associations. > I join a patch that add a "handleBidirectionalAssociations" option to the > hibernate namespace. When this option is enable, the getter and setter of the > bidirectional associations are modified so that synchronization of bother > ends is automatically handled. > For this, I do the following: > The property is renamed with a Internal suffix. There is a usual > getter/setter for this internal attribute, but with a package protected > visibility. > The hibernate mapping file are modified to point to this internal attribute. > An Accessor class is created on the same package as the entity class that > has public static method that allows direct access to the internal property. > For a *-to-One relation, usual getter, setter are generated, that > automatically handle other end of the association, using the Accessor if > needed. > For a *-to-Many relation, 4 methods are created: getter, setter, adder and > remover. All handle bidirectionality. The getter should return an > unmodificable collection but this is still to do because finding the correct > Collections.unmodifiableXXX to use does not seem that easy. > I join the patch as well as the meta-facade model > -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.andromda.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira ------------------------------------------------------------------------------ Register Now for Creativity and Technology (CaT), June 3rd, NYC.
