Detailed Description

A reader for polygons and pois stored in XML-format.

Reads pois stored as XML definition. The definitions must match the format POLYCONVERT generates.

Member Function Documentation

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

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

The inherited method called when characters occured.

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 176 of file GenericSAXHandler.cpp.

References TplConvert::_2str(), and GenericSAXHandler::myCharactersVector.

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

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

Handler for XML-errors.

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

Parameters

Loads pois/polygons assumed to be stored as XML.

If the option "xml" is set within the given options container, an instance of PCLoaderXML is built and used as a handler for the files given in this option.

Parameters
[in]ocThe options container to get further options from
[in]toFillThe poly/pois container to add loaded polys/pois to
[in]tmThe type map to use for setting values of loaded polys/pois
Exceptions

Callback method for characters to implement by derived classes.

Called by "endElement" (see there).

Parameters

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.
