Examples of helma.framework.repository.Resource

helma.framework.repository.Resource
Resource represents a pointer to some kind of information (code, skin, ...) from which the content can be fetched

     *  other locations or database stored skins. If parentName and
     *  subName are defined, the skin may be a subskin of another skin.
