In Python 2.6 you can use operator.methodcaller() to do this:
def invokeAll(method, data):
caller = operator.methodcaller(method, data)
return map(caller, contents)
> mycontent = ContentA()
> contents.append(mycontent)
This is not so bad. You could also make a class member of the base
class that keeps track of instances:
class ContentA(object):
contents = []
def __init__(self):
contents.append(self)
