Detailed Description

The base class for SUMO-native route handlers.

As both the SUMO-routes and the SUMO-route alternatives handlers share a set of processing functions, we've joined these functions within a single class (this one).

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 ROTypedXMLRoutesLoader::endDocument ( )
inherited

Called when the document has ended.

Todo:
Recheck usage of route loaders; it is not very fine to have one that use a parser and other that do not

Definition at line 83 of file ROTypedXMLRoutesLoader.cpp.

References ROTypedXMLRoutesLoader::myEnded.

bool ROTypedXMLRoutesLoader::ended ( ) const
inlineinherited

Returns the information whether no routes are available from this loader anymore.

Returns
Whether the whole input has been processed

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

Returns
The least time step that was read by this reader

Callback method for characters to implement by derived classes.

Called by "endElement" (see there).

Parameters
[in]elementThe opened element, given as a int

Adds routes from the file until the given time is reached.

Parameters

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
