[Zope] 'helper' classes in External Methods

[Tony McDonald]

Can someone give me a pointer to what these helper classes actually 
do? Can I use them to setup lists and dictionaries that will be used 
over the lifetime of the Zope server?

This is an example from an external method that Pavlos posted a while back.

class MCQ:
         ''' helper class for MCQ system'''
         def __init__(self, score):
                 ''' constructor'''
                 self.score = 0
                 self.total_score = 0

What I would like to do is load up a template_lookups dictionary with 
quite a few entries;

for template_id in self.Actors.RENDER.objectIds():
         renderer = eval("self.Actors.RENDER.%s" % template_id)
         template_lookups[template_id] = renderer

Thing is, I need access to the ZODB in one of my methods later in the 
module and so the above code doesn't work (too many 'selfs'!).

Anyone got any ideas?
tone.
