[Zope-dev] The object hierarchy

[Michael Collins]

I've been fiddling with zope for about a week now, and I'm just trying to 
figure out this little hole in the object hierarchy so that I can get relly 
working on my project.  I'm not entirely sure what vocabulary to use yet, so 
please bear with me.

I'm trying to navigate around the object hieararchy, and I can find a single 
object's subobjects by using hasattr and so on, but what if I want to navigate 
to a different position in the hieararchy?  As far as I can tell, objects 
don't have a pointer to their parent, so I've got a couple of options - find 
the root (which is preferable), or stuff an arbitrary root into a global 
variable for later use.  Ideally, I'd like the former course.
