static void vpXmlParser::cleanup ( )

inlinestaticinherited

As stated in http://xmlsoft.org/html/libxml-parser.html#xmlCleanupParser to clean up memory allocated by the xml2 library itself, the user should call xmlCleanupParser() only when the process has finished using the xml2 library. In case of doubt abstain from calling this function or do it just before calling exit() to avoid leak reports from valgrind ! That's why in ViSP the destructor doesn't call xmlCleanupParser(). Rather we provide the static function vpXmlParser::cleanup() that calls xmlCleanupParser() that could be called just before exit().

Examples:: mbtEdgeKltTracking.cpp, mbtEdgeTracking.cpp, mbtKltTracking.cpp, testXmlParser.cpp, tutorial-detection-object-mbt.cpp, tutorial-mb-edge-tracker.cpp, tutorial-mb-hybrid-tracker.cpp, and tutorial-mb-klt-tracker.cpp.

void vpXmlParser::save	(	const std::string &	filename,
		const bool	append = `false`
	)

inherited

Save the content of the class in the file given in parameters. The data of the class are in the child class. This method calls the write_main_class method which has to be implemented for every class depending on the data to save.

Parameters

filename	: the name of the file used to record the data
append	: if true and if the file exists, the data will be added to the data already in the file

void vpXmlParser::setMainTag ( const std::string & tag )

inlineinherited

set the name of the main tag

The main tag corresponds to the name of the root node

Parameters

tag	: name of the root node of the document

Definition at line 280 of file vpXmlParser.h.

Referenced by vpMbXmlParser::init().

void vpXmlParser::setMap ( const std::map< std::string, int > & _map )

inlineinherited

Set the map describing the data to parse. This map stores the name of each node and an associated key used to simplify the parsing of the file.

If the following file want to be parsed:

<config>
  <range>5</range>
  <step>7</step>
  <size_filter>3</size_filter>
</config>

The following map has to be declared:

std::map dataToParse;
dataToParse["config"] = 0;
dataToParse["range"] = 1;
dataToParse["step"] = 2;
dataToParse["size_filter"] = 3;

Or, you can use keyzord instead of number as key but it implies to declare in the child class an enumeration type of the name. For example:

typedef enum{
  config,
  range,
  step,
  size_filter} data_enum;
std::map dataToParse;
dataToParse["config"] = config;
dataToParse["range"] = range;
dataToParse["step"] = step;
dataToParse["size_filter"] = size_filter;

Parameters

_map	: the map describing the data to parse
