setClassMapping(nodeClass: Class;
mappedClass: Class) updating;
The setClassMapping method of the JadeXMLDocumentParser class enables you to specify the class of tree instances created during parsing; for example:
setClassMapping(JadeXMLElement, MyElement);
This method sets the mapping of the JadeXMLNode class specified in the nodeClass parameter to the user-specified class in the mappedClass parameter.
When creating persistent documents, an exception is raised if all concrete JadeXMLNode classes are not mapped to user subclasses.
