[ZODB-Dev] Re: Dynamically Updating Objects

[Chris S]

I think I may have found a similar feature in ZODB, but I'm not sure
how I'm supposed to access it. In connection.py, the docstring for
resetCaches() mentions it's used by Zope's refresh feature, and that
objects are refreshed after connections are reopened. Is the only way
to refresh classes in ZODB to first close all connections, call
resetCaches(), then reopen the connections?
