Since it's private, you cannot call it from outside the class--not from its superclasses nor any subclasses. Since it cannot be exposed in the class's API, there's no point in forcing a particular name. If you are using the Template Method pattern [1], make the method protected. This allows the superclass that declares the abstract method to call it and forces its subclasses to implement it given the name you decide. David [1] http://c2.com/cgi/wiki?TemplateMethodPattern
