RE: [eclipselink-users] Techniques for interrogating what objectsare held in EclipseLink 1.0.1 cache?
|

That worked fine once I saw from source code inspection that I should

Record argument as well. A bit cleaner than what I was originally
attempting.
Best regards,
Doug

Take a look at the "getAllFromIdentityMap" methods.
