[Pharo-users] Notification on GC of an object?

Hi all, does anybody here have experience with hooking into the GC mechanism so that an object gets notified when it is collected? I have a setup here with auto generated classes that I would like to remove when their unique instance disappears. So I’d like to let the GC figure out all the complicated tracking and inform me whenever such an object is collected, then I’ll zap the class as well. Experience reports, hints and tips are most welcome! ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile
