2014-07-04Changed FunctionTransform result type to node-setAdrian Kummerlaender
* using xalan::FormatterToXercesDOM internally ** this required changes to the TransformationFacade::generate member method overloads * TransformationFacade::generate now accepts references to xalan::FormatterListener instances ** "generate(std::basic_ostream<char>&..." instantiates a xalan::FormatterToXML and passes it to the actual generate member method * changed ResultNodeFacade's "getNode" method into a "getResultElement" method ** xalan::FormatterToXercesDOM requires a xercesc::DOMElement instance instead of the previously available xercesc::DOMNode instance ** changed FunctionReadDirectory accordingly * adapted FunctionTransform test case accordingly
2014-05-31Revamped external function result treesAdrian Kummerländer
* the root node of the result tree of each function is a domain element ** i.e. the root node of "read-xml-file" is "file", the root node of "read-directory" is "directory" * the root node contains the result state of the function call encoded in a "result" attribute ** possible values are "success" and "error" ** the root node may contain additional attributes such as the target path of a called transformation * the actual function result is contained within the child nodes of the function root node ** i.e. the XML file tree returned by "read-xml-file" is a child of the function root node ** if specific errors occured they are also returned as child nodes of the function root node *** this is currently only the case for "transform" where transformation errors are returned as "error" value node childs of the function root node * updated test cases accordingly
2014-05-24Implemented ResultNodeFacade as a DOM node construction helperAdrian Kummerländer
* wraps result node construction and appends it to root node on destruction * offers a simpler interface for common node construction patterns * simplifies result node construction in all external function implementations ** most noticeable in FunctionReadDirectory * expanded FunctionReadDirectory result nodes by name, extension, and full-path nodes
