NAME

Map::Tube::Glasgow - Interface to the Glasgow tube map

SYNOPSIS

    use Map::Tube::Glasgow;
    my $tube = Map::Tube::Glasgow->new();

    my $route = $tube->get_shortest_route('Cowcaddens', 'Bridge Street');

    print "Route: $route\n";

DESCRIPTION

This module allows to find the shortest route between any two given tube stations in Glasgow. All interesting methods are provided by the role Map::Tube.

METHODS

CONSTRUCTOR

    use Map::Tube::Glasgow;
    my $tube = Map::Tube::Glasgow->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 glasgow-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.
