Subject Query to return shared data for performance reasons.
Date Thu, 03 Jul 2008 15:31:18 GMT

Im interested in helping openjpa to implement that query can return 
shared objects from the cache.

On many usage cases its only of interest to read data, no need to get a 
clone/copy then.
(and yes its up to the user to not actually edit the returned data.)

This exists in eclipselink and works good, QueryHints.READ_ONLY.

Could i please get some initial help,  where to do this in the code base 
in a nice way ?.
