It 00045 //- is very common to want to be able to extract a portion of a document's 00046 //- tree or to create a new fragment of a document. Imagine implementing a 00047 //- user command like cut or rearranging a document by moving fragments 00048 //- around. It is desirable to have an object which can hold such fragments 00049 //- and it is quite natural to use a Node for this purpose. While it is true 00050 //- that a Document object could fulfil this role, a Document object can 00051 //- potentially be a heavyweight object, depending on the underlying 00052 //- implementation. What is really needed for this is a very lightweight 00053 //- object. DocumentFragment is such an object.</p> 00054 //- <p>Furthermore, various operations -- such as inserting nodes as children 00055 //- of another Node -- may take DocumentFragment objects as arguments; this 00056 //- results in all the child nodes of the DocumentFragment being moved to the 00057 //- child list of this node.</p> 00058 //- <p>The children of a DocumentFragment node are zero or more nodes 00059 //- representing the tops of any sub-trees defining the structure of the 00060 //- document. DocumentFragment nodes do not need to be well-formed XML documents 00061 //- (although they do need to follow the rules imposed upon well-formed XML 00062 //- parsed entities, which can have multiple top nodes). For example, a 00063 //- DocumentFragment might have only one child and that child node could be 00064 //- a Text node. Such a structure model represents neither an HTML document 00065 //- nor a well-formed XML document.</p> 00066 //- <p>When a DocumentFragment is inserted into a Document (or indeed any 00067 //- other Node that may take children) the children of the DocumentFragment 00068 //- and not the DocumentFragment itself are inserted into the Node. This 00069 //- makes the DocumentFragment very useful when the user wishes to create 00070 //- nodes that are siblings; the DocumentFragment acts as the parent of these 00071 //- nodes so that the user can use the standard methods from the Node interface, 00072 //- such as insertBefore() and appendChild().</p> 00073 class CL_DomDocumentFragment : public CL_DomNode 00074 { 00076 public: 00077 //: Constructs a DOM Document Fragment handle. 00078 CL_DomDocumentFragment(); 00079 00080 CL_DomDocumentFragment(CL_DomDocument &doc); 00081 00082 CL_DomDocumentFragment(const CL_SharedPtr<CL_DomNode_Generic> &impl); 00083 00084 ~CL_DomDocumentFragment(); 00085 }; 00086 00087 #endif
