Hi all. I have a question about design. The general question would be: Where is the line beteween extending a class and adding new methods to that class?
And the particular case im involved is: I have a class (say USERCLASS) who implements a user interface. One of his methods is called `login'. Later on i got the order of implementing a `single login', which off course means a single user cant login if a session is already started for that user. Extending comes to my mind at first (it works good, actually). But now im thinikng if there some problem in adding a method to the USERCLASS class named single_login(), who will take care of applying the rules of single sign on. Which one you guys will pick up? USERCLASS().single_login() or SINGLELOGINUSERCLASS().login() Thanks for your oppinions! Gerardo -- http://mail.python.org/mailman/listinfo/python-list
