In the latest Zope source, I've noticed calls to inheritedAttribute in
the Python code.
I've found the C source code in ExtensionClass.c, but it doesn't help me
understand when I should use it from Python, and why.
*reads more source*
Ah! About 70 lines further on in ExtensionClass.c:
"inheritedAttribute(class,name) -- Get an inherited attribute\n\n"
"Get an attribute that would be inherited if the given (extension)\n"
"class did not define it. This method is used when overriding\n"
"inherited methods. It provides 2 advantages over accessing\n"
"\n"
"attributes directly through a superclass:\n"
"\n"
"1. The superclass need not be known,\n"
"\n"
"2. The superclass may be a Python class. Without this method, it
would\n"
" be possible to override methods inherited from python classes
because\n"
" unbound methods gotten from Python classes cannot be called with
\n"
" extension class instances. \n"
Is there some documentation of this on zope.org or dev.zope.org that
I've missed?
Thanks.
