observing a reference variable's instance

[Pieter Breed]

Hi,

I would like to have a reference to class instance, but not influence
when it should or should not be garbage collected. Is this possible?

I have a cache of objects that I use to send update signals with. The
cache manager should allow these instances to go out of scope and be
garbage collected, in other code. Normally the cache's reference to
the instance will prevent that instance from being collected. Is there
a way around this?

Regards,
Pieter

Use the WeakReference class.
