NAME Map::Tube::Nanjing - Interface to the Nanjing Metro Map. SYNOPSIS use Map::Tube::Nanjing; my $obj = Map::Tube::Nanjing->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 = $obj->xml; DESCRIPTION It currently provides functionality to find the shortest route between the two given nodes. For more information about Nanjing Map, click here <https://en.wikipedia.org/wiki/Nanjing_Metro>. METHODS "new()" Constructor. "get_all_routes($from, $to)" [EXPERIMENTAL] Get all routes from station to station. Returns reference to array with Map::Tube::Route objects. "get_line_by_id($line_id)" Get line object defined by id. Returns Map::Tube::Line object. "get_line_by_name($line_name)" Get line object defined by name. Returns Map::Tube::Line object. "get_lines()" Get lines in metro map. Returns reference to unsorted array with Map::Tube::Line objects. "get_node_by_id($station_id)" Get station node by id. Returns Map::Tube::Node object. "get_node_by_name($station_name)" Get station node by name. Returns Map::Tube::Node object. "get_shortest_route($from, $to)" Get shortest route between $from and $to node names. Node names in $from and $to are case insensitive. Returns Map::Tube::Route object. "get_stations($line)" Get list of stations for concrete metro line. Returns reference to array with Map::Tube::Node objects. "name()" Get metro name. Returns string with metro name. "xml()" Get XML specification of Nanjing metro. Returns string with XML.
