Deleting an instance

Is there a way to delete/remove/kill an instance other than by quitting and
starting Pharo up again?

In my example, I installed the ContactListEditor package from
http://www.pharocasts.com/2011/02/pharo-gui-with-polymorph.html

After several "ContactListEditor open" doIts, I closed most of the windows.
I inspected "ContactListEditor allInstances" and it has an array of instances,
one for each 'doIt'. The instances are still 'alive', including those whose
windows were closed.

If I save and quit Pharo, and restart it, the only instances that are alive are
the ones that have open windows.

Re: Deleting an instance

If instance is not referenced anymore, you can:

Smalltalk garbageCollect.

If still here, you can search (but not easy) for references with:

PointerExplorer new openExplorerFor: myInstance.

Re: Deleting an instance

Hi. No, in most object oriented languages there is no other way to remove an object that remove all the references to it and then force a garbage collector.

As Laurent suggested, in this case, the better option is to explore the pointers to such objects to see who are ponting to it.
