Thx for the explanation - that's exactly what I meant asking why it is protected?
I would like to have the interface public - because a marker is rather useless if It cannot be referenced. I wanted to use it in an interface as argument but I had to use the class instead - which I think is not ok when I just want to specify the expected interface. I think it is ok to offer a class to extend for easy living... but 'hiding' the interface and forcing to extend a class is not ok. Is it ok if I change it to public? 2008/8/5 Lukas Lang <[EMAIL PROTECTED]>: > Hello folks, > > according to Sun's guide to classes and objects [1], > classes or interfaces, having no keyword as "public", > "private" or "protected" prefixed offer default visibility. > > As the guide propagates, an interface providing default visibility > is not visible from other packages, which would represent a problem for one, > who wants to derive from the Nature interface in various other packages. > > The main intention to do so, was that we offered a base class (BaseNature) > to do easy property handling (prefixing) and a "health check" in the > constructor, > which is visible to all packages. > > You can see the Nature interface itself as a kind of marker > to have a common superclass. > > I think, I got some documentation (UML) on the Nature architecture. > So if you want, I can provide this to you. > > Regards, > Lukas > > [1] http://java.sun.com/docs/books/tutorial/java/javaOO/accesscontrol.html > > Werner Guttmann schrieb: >> >> Joachim, >> >> sorry, but the keyword 'protected' is not used in the interface >> declaration anywhere.
