Imagine implementing a user command like cut or rearranging a * document by moving fragments around. It is desirable to have an object * which can hold such fragments and it is quite natural to use a DOMNode for * this purpose. While it is true that a DOMDocument object could * fulfil this role, a DOMDocument object can potentially be a * heavyweight object, depending on the underlying implementation. What is * really needed for this is a very lightweight object. * DOMDocumentFragment is such an object. *

Furthermore, various operations -- such as inserting nodes as children * of another DOMNode -- may take DOMDocumentFragment * objects as arguments; this results in all the child nodes of the * DOMDocumentFragment being moved to the child list of this node. *

The children of a DOMDocumentFragment node are zero or more * nodes representing the tops of any sub-trees defining the structure of the * document. DOMDocumentFragment 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 DOMDocumentFragment might have only one * child and that child node could be a DOMText node. Such a * structure model represents neither an HTML document nor a well-formed XML * document. *

When a DOMDocumentFragment is inserted into a * DOMDocument (or indeed any other DOMNode that may take * children) the children of the DOMDocumentFragment and not the * DOMDocumentFragment itself are inserted into the * DOMNode. This makes the DOMDocumentFragment very * useful when the user wishes to create nodes that are siblings; the * DOMDocumentFragment acts as the parent of these nodes so that the * user can use the standard methods from the DOMNode interface, * such as insertBefore() and appendChild(). * * @since DOM Level 1 */ class CDOM_EXPORT DOMDocumentFragment: public DOMNode { protected: // ----------------------------------------------------------------------- // Hidden constructors // ----------------------------------------------------------------------- /** @name Hidden constructors */ //@{ DOMDocumentFragment() {}; //@} private: // ----------------------------------------------------------------------- // Unimplemented constructors and operators // ----------------------------------------------------------------------- /** @name Unimplemented constructors and operators */ //@{ DOMDocumentFragment(const DOMDocumentFragment &); DOMDocumentFragment & operator = (const DOMDocumentFragment &); //@} public: // ----------------------------------------------------------------------- // All constructors are hidden, just the destructor is available // ----------------------------------------------------------------------- /** @name Destructor */ //@{ /** * Destructor * */ virtual ~DOMDocumentFragment() {}; //@} }; XERCES_CPP_NAMESPACE_END #endif
