A class must support encapsulation, inheritance and polymorphism. If it doesn't, then it isn't a class. The same way, a method is a function that belongs to a class and can be public, private or protected. If a function is external to an object (i.e. it can't be made private or protected) than it isn't a method. -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
