This - * way KURL will remain a generic parser capable of parsing any - * generic URL that adheres to specifications. - * - * The KURIFilter class applies a number of filters to a URI, - * and returns the filtered version whenever possible. The filters - * are implemented using plugins to provide easy extensibility - * of the filtering mechanism. That is, new filters can be added in - * the future by simply inheriting from @ref KURIFilterPlugin and - * implementing the @ref KURIFilterPlugin::filterURI method. - * - * Use of this plugin-manager class is straight forward. Since - * it is a singleton object, all you have to do is obtain an instance - * by doing @p KURIFilter::self() and use any of the public member - * functions to preform the filtering. - * - * @sect Example - * - * To simply filter a given string: - * <pre> - * bool filtered = KURIFilter::self()->filterURI( "kde.org" ); - * </pre> - * - * You can alternatively use a KURL: - * <pre> - * KURL url = "kde.org"; - * bool filtered = KURIFilter::self()->filterURI( url ); - * </pre> - * - * If you have a constant string or a constant URL, - * simply invoke the corresponding function to obtain - * the filtered string or URL instead of a boolean flag: - * <pre> - * TQString u = KURIFilter::self()->filteredURI( "kde.org" ); - * </pre> - * - * You can also specify only specific filter(s) to be applied - * by supplying the name(s) of the filter(s). By defualt all - * filters that are found are loaded when the KURIFilter object - * is created will be used. These names are taken from the - * enteries in the \".desktop\" files. Here are a couple of - * examples: - * <pre> - * TQString text = "kde.org"; - * bool filtered = KURIFilter::self()->filterURI( text, "KShortURIFilter" ); - * - * TQStringList list; - * list << "KShortURIFilter" << "MyFilter"; - * bool filtered = KURIFilter::self()->filterURI( text, list ); - * </pre> - * - * KURIFilter also allows richer data exchange through a simple - * meta-object called @p KURIFilterData.
