Detailed Description

Loader for the of turning percentages and source/sink definitions.

This handler parses XML-descriptions of jtrrouter-definitions, including percentage ratios at junctions and definitions of sink/source edges.

All read values are stored directly into the given network's structures (edges).

Member Function Documentation

void ROJTRTurnDefLoader::addToEdge ( const SUMOSAXAttributes attrs)
private

Parses the probability to use a certain outgoing edge.

Tries to retreive the outgoing edge and then the probability to use it. If one of both operations could not be accomplished, an error is generated.

If everything is ok, this means the destination edge is defined and known and the probability is valid, too, this probability is added to "myEdge", the last parsed incoming edge. As time, the previously parsed interval begin/end is used.

Parameters
[in]attrsThe SAX-attributes to parse the destination edge and the probability to use it from

void ROJTRTurnDefLoader::beginFromEdge ( const SUMOSAXAttributes attrs)
private

Begins the processing of a incoming edge definition.

Tries to retrieve the currently described incoming edge. If the edge id is not given in the attributes or the edge is not known, an error is reported.

If everything is ok, the edge's address is stored in myEdge.

Parameters
[in]attrsThe SAX-attributes to parse incoming edge from

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

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
[in]exceptionThe occured exception to process
Exceptions

Callback method for characters to implement by derived classes.

Called by "endElement" (see there).

Parameters
[in]elementThe opened element, given as a int
[in]charsThe complete embedded character string ProcessError These method may throw a ProcessError if something fails

Reimplemented in NIImporter_ITSUMO::Handler.

void GenericSAXHandler::startElement ( const XMLCh *const  uri,
const XMLCh *const  localname,
const XMLCh *const  qname,
const XERCES_CPP_NAMESPACE::Attributes &  attrs 
)
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
