Resource unload doenst free memory? [message #430920] Wed, 17 June 2009 17:51 Go to next message

Hi,

I'm working with a big model, which is splitted in several resources.
I've written a cleaner thread, which unloads all unused resources (using
resouce.unload()). Still, all elements are in one big containment tree.
So unloading "proxyfies" these elements. But the problem is, that the
memory footprint doesn't drop? Is unload not ment for these kind of
issues, am I doing something wrong and is there another possibility?

Greetings,
Otto

Otto,

Yes, in this regard EMF currently works as designed although this
knowledge is not too wide-spread. For this reason I blogged about the
internal details some while back. You might find this reading
interesting:

Hi Eike,

Thanks for the link, it is indeed a very interesting reading.

You mention that you have seen EStore implementations which maintain a separate store instance for all objects of a resource. Do you have more details about that approach.

Thanks & best regards!
