% of unused objects?

Hi Alexandre. Sorry I didn't answer before...I don't read emails while ESUG ;)

First, you need an specific modified VM. I can send it by email or upload it somewhere if you want.

To get that statistics and some more, you have to download the package UnusedObject  from  http://www.squeaksource.com/UsedObjects

Check the class UnusedObjectDiscoverer and its tests. But basically the idea is this:

You first evaluate  "UnusedObjectDiscoverer current startDiscovery."

Once that is done....is your time to do what you want to analyze....run tests, open a workspace, do whatever you want. When you are done, inspect or print the result of: "UnusedObjectDiscoverer current stopDiscoveryAndGetStadistics "

And that's all for the moment ;)

Ahhh I did some Moose DistributionMap if you want. For that you need to load also the package UsedObjectsMoose on a Moose image, and run the class side examples of the class UsedObjectsDistributionMap

Last thing: I condiser an object was used, when it received  at least one message.

Cheers
