-------------------------------------

Is there a patch for this issue?
                
> Extend PersistenceManageFactory to return all known entity classes
> ------------------------------------------------------------------
>
>                 Key: JDO-667
>                 URL: https://issues.apache.org/jira/browse/JDO-667
>             Project: JDO
>          Issue Type: New Feature
>          Components: api, specification, tck
>    Affects Versions: JDO 3 (3.0)
>            Reporter: Marco
>             Fix For: JDO 3 maintenance release 1 (3.1)
>
>
> JDO 3 now has the ability to declare meta-data programmatically. Part of this 
> feature is the ability to ask the PersistenceManagerFactory via the method 
> getMetadata(java.lang.String) for the meta-data of one single class. But 
> there is no way to list all known classes.
> I therefore kindly ask for a new method in PersistenceManagerFactory like 
> this:
> Collection<String> getClassesWithMetadata();
> Btw., this is Andy's suggestion posted here: 
> http://www.datanucleus.org/servlet/forum/viewthread_thread,6379#33224
> I'd greatly appreciate, if this method became a part of JDO 3.1.
> Edit 1: I just saw the various overloaded methods getManagedObjects(...) in 
> PersistenceManager - maybe the alternative method name "getManagedClasses()" 
> would be more consistent?
