NAME

Map::Tube::Singapore - Interface to the Singapore Metro Map.

SYNOPSIS

use Map::Tube::Singapore;
my $obj = Map::Tube::Singapore->new;
my $routes_ar = $obj->get_all_routes($from, $to);
my $line = $obj->get_line_by_id($line_id);
my $line = $obj->get_line_by_name($line_name);
my $lines_ar = $obj->get_lines;
my $station = $obj->get_node_by_id($station_id);
my $station = $obj->get_node_by_name($station_name);
my $route = $obj->get_shortest_route($from, $to);
my $stations_ar = $obj->get_stations($line);
my $metro_name = $obj->name;
my $xml_file = $obj->xml;
