Subject: [JDO] Help Needed!
Date: Mon, 30 Aug 2004 09:03:11 -0400

Hi again all. As lots of people said they wanted to help work on JDO 
stuff, some things we need which are somewhat autonomous:


Support for equals criteria which matches object identity, so:

criteria.addEqualTo("objectReferenceOnCandidate", myWombat);

which will generate the correct code to match pk/fk


Support for a contains criteria:

criteria.addContains("collectionOnCandidate", myWombat);

which will generate correct where criteria. This one will be fun. This 
will need to support object identity based query building like the 
object reference equals.


Fetch Groups:

Read the JDO spec for explanation of this one. Is good stuff. Basically 
override of proxy settings in our terms on a per-query basis.


JDO 2.0 Style mapping definitions:

Read the JDo spec for this one. Basically an alternate way of defining 
mappings.


Any help on these is greatly appreciated! Thank you!

-Brian
