Hi Tom, Because I would only like to delete those that are not in use... just like Garbage Collection. If I just removed every reference I could not achieve identity allocation ( which is a requirement ).
To clarify: Suppose you are coding an email user interface, like GMail, where there are potentially thousands of distincts messages. You are modeling messages using a value object ( EmailVO ) that holds substantial data ( subject, sender, text, etc ). Now, for some reason, you MUST make sure that there is one EmailVO instance exists per-email at a given moment in time ( I repeat, this is an important requirement in my case ). See... I need a factory with a cache that knows how to return the singleton copy of each EmailVO ( based on a hash of the email ID or something like that ) BUT that is smart enough to allow for GC. While some of these emails will surface constantly at the user interface ( while reading a thread ) others will only be used for mere seconds and will never appear again. It makes sense to remove the latter from memory... specially when we are approaching six figures in magnitude.
