Re: [Pyode-user] Individual Space classes

[Matthias B. <ba...@ir...>]

Hi,

I have implemented the previously mentioned space restructuring 
(SpaceBase, SimpleSpace, HashSpace, QuadTreeSpace classes and a factory 
function Space). Now there's a problem with the XODE reader because it's 
assuming ode.Space is a class and not a function (e.g. when using 
isinstance()). The unit test produces exceptions like this:

   File "C:\PROGRA~1\PROGRA~1\Python23\Lib\site-packages\xode\geom.py", 
line 20, in __init__
     self._space = self.getFirstAncestor(ode.Space).getODEObject()
   File "C:\PROGRA~1\PROGRA~1\Python23\Lib\site-packages\xode\node.py", 
line 209, in getFirstAncestor
     if (isinstance(parent.getODEObject(), type)):
TypeError: isinstance() arg 2 must be a class, type, or tuple of classes 
and types

So is this a real problem or can it be easily fixed? (you could use 
SpaceBase instead of Space. However, I don't know if you have to be able 
to create instances of the class you're using. You can't create 
instances from SpaceBase)

By the way, what kind of Space will the XODE reader create? By browsing 
through the XODE spec it seems there's no way to specify which space 
should be used...(or did I miss something?).
