It is + * desirable to have an object which can hold such fragments and it is + * quite natural to use a Node for this purpose. While it is true that + * a \c Document object could fulfil this role, a + * \c Document object can potentially be a heavyweight object, + * depending on the underlying implementation. What is really needed + * for this is a very lightweight object. \c DocumentFragment + * is such an object. + * + * Furthermore, various operations -- such as inserting nodes as + * children of another \c Node -- may take + * \c DocumentFragment objects as arguments; this results in all + * the child nodes of the \c DocumentFragment being moved + * to the child list of this node. + * + * The children of a \c DocumentFragment node are zero or + * more nodes representing the tops of any sub-trees defining the + * structure of the document. \c DocumentFragment nodes do + * not need to be well-formed XML documents (although they do need to + * follow the rules imposed upon well-formed XML parsed entities, + * which can have multiple top nodes). For example, a + * \c DocumentFragment might have only one child and that child + * node could be a \c Text node. Such a structure model + * represents neither an HTML document nor a well-formed XML document. + * + * When a \c DocumentFragment is inserted into a + * \c Document (or indeed any other \c Node that may + * take children) the children of the \c DocumentFragment + * and not the \c DocumentFragment itself are inserted + * into the \c Node . This makes the + * \c DocumentFragment very useful when the user wishes to create + * nodes that are siblings; the \c DocumentFragment acts + * as the parent of these nodes so that the user can use the standard + * methods from the \c Node interface, such as + * \c insertBefore() and \c appendChild() . + * + */ +class TDEHTML_EXPORT DocumentFragment : public Node +{ + friend class Document; + friend class HTMLElementImpl; + friend class Range; + +public: + DocumentFragment(); + DocumentFragment(const DocumentFragment &other); + DocumentFragment(const Node &other) : Node() + {(*this)=other;} + + DocumentFragment & operator = (const Node &other); + DocumentFragment & operator = (const DocumentFragment &other); + + ~DocumentFragment(); + +protected: + DocumentFragment(DocumentFragmentImpl *i); +}; + +class NamedNodeMap; +class DOMString; + +/** + * Each \c Document has a \c doctype attribute + * whose value is either \c null or a \c DocumentType + * object.
