[Zope] persistent object with non-persistent attributes

[Jerome Alet]

Hi,

I would like to create a python Zope product which allows me
to create persistent objects.

but these objects have (as subobjects ?) complex attributes which
are themselves instances of a non-Zope related class, and which
should not be persistent (think hardware plug&play), because
they are recreated every time a method is called on my instance.

I think I could do (untested) :

  myZopePersistentClassInstance.complexAttr = myNonZopeClass()
        
but this will probably, if it works, bloat by ZODB.
 
is there a way to do this without suffering from severe bloat ?

thanks in advance

PS: I know this may not be very clear...
