◆ buildErrorMessage()

std::string GenericSAXHandler::buildErrorMessage ( const XERCES_CPP_NAMESPACE::SAXParseException &  exception)
protectedinherited

Builds an error message.

The error message includes the file name and the line/column information as supported by the given SAXParseException

Parameters
[in]exceptionThe name of the currently processed file
Returns
A string describing the given exception

◆ characters()

void GenericSAXHandler::characters ( const XMLCh *const  chars,
const XERCES3_SIZE_t  length 
)
inherited

The inherited method called when characters occurred.

The retrieved characters are converted into a string and appended into a private buffer. They are reported as soon as the element ends.

Todo:

recheck/describe what happens with characters when a new element is opened

describe characters processing in the class' head

Definition at line 169 of file GenericSAXHandler.cpp.

References GenericSAXHandler::myCharactersVector, and StringUtils::transcode().

◆ convert()

XMLCh * GenericSAXHandler::convert ( const std::string &  name) const
privateinherited

converts from c++-string into unicode

Todo:
recheck encoding
Parameters
[in]nameThe string to convert
Returns
The string converted into a XMLCh-string

Definition at line 80 of file GenericSAXHandler.cpp.

Referenced by GenericSAXHandler::GenericSAXHandler().

◆ convertTag()

int GenericSAXHandler::convertTag ( const std::string &  tag) const
privateinherited

Converts a tag from its string into its numerical representation.

Returns the enum-representation stored for the given tag. If the tag is not known, SUMO_TAG_NOTHING is returned.

Parameters
[in]tagThe string to convert
Returns
The int-value that represents the string, SUMO_TAG_NOTHING if the named attribute is not known

◆ endElement()

void GenericSAXHandler::endElement ( const XMLCh *const  uri,
const XMLCh *const  localname,
const XMLCh *const  qname 
)
inherited

The inherited method called when a tag is being closed.

This method calls the user-implemented methods myCharacters with the previously collected and converted characters.

Then, myEndElement is called, supplying it the qname converted to its enum- and string-representations.

Todo:

recheck/describe encoding of the string-representation

do not generate and report the string-representation

◆ error()

void GenericSAXHandler::error ( const XERCES_CPP_NAMESPACE::SAXParseException &  exception)
inherited

Handler for XML-errors.

The message is built using buildErrorMessage and thrown within a ProcessError.

Parameters
[in]exceptionThe occurred exception to process
Exceptions
ProcessErrorOn any call

◆ fatalError()

void GenericSAXHandler::fatalError ( const XERCES_CPP_NAMESPACE::SAXParseException &  exception)
inherited

Handler for XML-errors.

The message is built using buildErrorMessage and thrown within a ProcessError.

Exceptions

Parameters
[in]exceptionThe occurred exception to process

void GenericSAXHandler::startElement ( const XMLCh *const  uri,

inherited

The inherited method called when a new tag opens.

The method parses the supplied XMLCh*-qname using the internal name/enum-map to obtain the enum representation of the attribute name.

Then, "myStartElement" is called supplying the enumeration value, the string-representation of the name and the attributes.

Todo:

recheck/describe encoding of the string-representation

do not generate and report the string-representation
