Re: [eclipselink-dev] SessionCustomizer instance via EMF property

Thanks for the reply. After reading your response, and re-reading my original post I see that I wasn't clear / misspoke. Let me try this again. 

I want to be able to pass a SessionCustomizer instance in as a property to Persistence.createEntityManagerFactory(...) / PersistenceProvider.createContainerEntityManagerFactory(...). I don't want to change the meaning / semantics of SessionCustomization. I only want to be able to provide an instance as opposed to a String Class name.

Thanks,

Rick

Rick,

I believe its historical where the session customization was generally focussed on the EMF/ServerSession. The only caution I offer is that users would need to understand that this usage should be limited to customizing features of the specific EM/UnitOfWork/ClientSession and not setting of the shared ServerSession.

As an example if in a customizer you accessed the descriptor for an entity class and changed a setting it would effect the entire EMF.
