NAME
Map::Tube::KoelnBonn - Interface to the Koeln-Bonn U- and S-Bahn and tram maps
SYNOPSIS
use Map::Tube::KoelnBonn;
my $tube = Map::Tube::KoelnBonn->new();
my $route = $tube->get_shortest_route('Wurzerstr.', 'Plittersdorf');
print "Route: $route\n";
DESCRIPTION
This module allows to find the shortest route between any two given tube stations in Köln and Bonn. In fact, underground, tramway, and S-Bahn lines are covered for the wider Köln-Bonn area (VRS). All interesting methods are provided by the role Map::Tube.
METHODS
CONSTRUCTOR
use Map::Tube::KoelnBonn;
my $tube = Map::Tube::KoelnBonn->new();
The only argument, xml
, is optional; if specified, it should be a code ref to a function that returns either the path the XML map file, or a string containing this XML content. The default is the path to koelnbonn-map.xml that is a part of this distribution. For further information see Map::Tube.
xml()
This read-only accessor returns whatever was specified as the XML source at construction.
ERRORS
If something goes wrong, maybe because the map information file was corrupted, the constructor will die.
