What do you mean by "garbage collection" in this context? Although I've toyed with the idea of using the Boehm collector, the current automatic memory management system (which I assume is what you're referring to) is just based on reference counts. > I went ahead and re-added transient views, essentially by moving the > createView() logic from the ViewFactory to the ViewImplementation, where > it can be overridden.

I think what I was planning on doing to address this is to have the vobject table on the site not increase the reference count. So, you could have a "transient" vobject which is still listed on the site, and is removed from the site's vobject table by the destructor. -- [ Peter Amstutz ][ [EMAIL PROTECTED] [EMAIL PROTECTED] [Lead Programmer][Interreality Project][Virtual Reality for the Internet] [ VOS: Next Generation Internet Communication][ http://interreality.org ] [ http://interreality.org/~tetron ][ pgpkey: pgpkeys.mit.edu 18C21DF7 ]
