I'm still struggling to learn all the rules of RPython, i have read the coding guide, and the PDF's PyGirl and Ancona's RPython paper, but still i feel i'm not fully grasping everything.
I have a function that returns different classes that all share a common base class. It works until i introduce a new subclass that has some methods of the same name. Then i get the demotion, can not follow, degenerated error. I googled, but all i can find is an IRC log where Fijal seems to taking talking about my problem. http://www.tismer.com/pypy/irc-logs/pypy/%23pypy.log.20070125 <fijal> pedronis: if function can return (in rpython) set of classes with common superclass, than all methods that I call later must be defined on that superclass, right? [11:30] <fijal> [15:01] <pedronis> yes, unless you assert a specific subclass So i just need to use an assert statement before the function return, and assert the class i am returning? I am blogging about my progress while learning RPython, i have posted about meta-programming in Rpython which is a new concept to me. http://pyppet.blogspot.com/2010/08/meta-programming-in-rpython.html -brett _______________________________________________ [email protected] http://codespeak.net/mailman/listinfo/pypy-dev
