Provides the callbacks for an XMLParser.
The various routines in this class will be called when corresponding elements of the XML file being parsed are encountered.
The routines in this class do nothing; you will need to create a derived class that overrides some or all of these routines to do the processing that you require.
regina::xml::XMLParserCallback::~XMLParserCallback | ( | ) | [inline, virtual] |
Default destructor that does nothing.
void regina::xml::XMLParserCallback::characters | ( | const std::string & | s | ) | [inline, virtual] |
Called when characters are encountered.
s | the characters encountered. |
Reimplemented in regina::NXMLCallback.
void regina::xml::XMLParserCallback::comment | ( | const std::string & | s | ) | [inline, virtual] |
Called when a comment is encountered.
s | the comment string. |
void regina::xml::XMLParserCallback::end_document | ( | ) | [inline, virtual] |
Called when the document is finalised.
Reimplemented in regina::NXMLCallback.
void regina::xml::XMLParserCallback::end_element | ( | const std::string & | n | ) | [inline, virtual] |
Called when an element's closing tag is encountered.
This is called immediately after start_element() if the opening tag is in <tag/>
format.

s | the error message. |
Reimplemented in regina::NXMLCallback.
void regina::xml::XMLParserCallback::fatal_error | ( | const std::string & | s | ) | [inline, virtual] |
Called when a parser fatal error occurs.
s | the error message. |
Reimplemented in regina::NXMLCallback.
void regina::xml::XMLParserCallback::start_document | ( | XMLParser * | parser | ) | [inline, virtual] |
Called at the start of the document.
parser | the XML parser that is currently parsing this document. |
Reimplemented in regina::NXMLCallback.
void regina::xml::XMLParserCallback::start_element | ( | const std::string & | n, |
const regina::xml::XMLPropertyDict & | p | ||
) | [inline, virtual] |
Called when an element's opening tag is encountered.
n | the name of the tag. |
p | a dictionary of all the properties of the tag. |
Reimplemented in regina::NXMLCallback.
void regina::xml::XMLParserCallback::warning | ( | const std::string & | s | ) | [inline, virtual] |
