See > http://www.perlmonks.org/index.pl?node_id=219378 Thanks for that. Knowing that Abigail has used this technique gives me confidence that it works! However, even now I know the name for the technique I don't think it'd be appropriate to call the module Class::InsideOutAttributes (or similar), because that is describing the module's implementation rather than the situation in which it is useful. > There was some discussion on writing a Class::MethodMaker-ish module > for this technique on PerlMonks, but it's very hard with the common > state of Perl affairs. I've never used Class::MethodMaker but it looks to be for helping you create a class that needs lots of get_*() and set_*() methods to exist for use by people creating objects in the class to get and set particular attributes without needing to know how it is implemented. Class::FakeAttributes helps in a different situation, where a class author is subclassing something that is based on, for example, a scalar ref but he/she wants to add instance data in the subclass. The methods in this class are intended to help the subclass author access the attributes inside the class definition, not to provide public methods for use by the people creating objects of that class. > I don't really think it merits a module that can't do about as much as > C::MM. I don't think it's a case of not doing as much as, but of doing something different. Many of my classes don't have get_*() and set_*() methods, nor would they benefit from having them. Class::FakeAttributes is designed to help with one specific situation, and I think giving it capabilities to help with something that applies independently of that situation would be confusing. But if the consensus of this list is that I should remove Class::FakeAttributes from Cpan then I shall do so. SmylersThread Previous | Thread Next
