Detailed Description

Importer of nodes stored in unsplit elmar format.

Being a LineHandler, this class retrieves each line from a LineReader and parses these information assuming they contain node definitions in DLRNavteq's unsplit format.

NodesHandler& NIImporter_DlrNavteq::NodesHandler::operator=

(

const NodesHandler &

)

[private]

Invalidated assignment operator.

bool NIImporter_DlrNavteq::NodesHandler::report

(

const std::string &

result

)

throw (ProcessError) [virtual]

Parsing method.

Implementation of the LineHandler-interface called by a LineReader; interprets the retrieved information and stores it into "myNodeCont". Additionally, edge geometries are parsed and stored into "myGeoms".

Parameters:

[in]

result

The read line

Returns:

Whether the parsing shall continue

Exceptions:

ProcessError

if something fails
