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.

EXAMPLE1

use strict;
use warnings;

use Encode qw(decode_utf8 encode_utf8);
use Map::Tube::Nanjing;

# Object.
my $obj = Map::Tube::Nanjing->new;

# Get route.
my $route = $obj->get_shortest_route(decode_utf8('鼓楼'), decode_utf8('大厂'));

# Print out type.
print "Route: ".encode_utf8($route)."\n";

# Output:
# Route: 鼓楼 (南京地铁1号线), 大厂 (宁天城际轨道交通)

EXAMPLE2

use strict;
use warnings;

use Map::Tube::Nanjing;

# Object.
my $obj = Map::Tube::Nanjing->new;

# Get XML file.
my $xml_file = $obj->xml;

# Print out XML file.
print "XML file: $xml_file\n";

# Output like:
# XML file: .*/nanjing-map.xml

EXAMPLE3

use strict;
use warnings;

use Map::Tube::GraphViz;
use Map::Tube::GraphViz::Utils qw(node_color_without_label);
use Map::Tube::Nanjing;

# Object.
my $obj = Map::Tube::Nanjing->new;

# GraphViz object.
my $g = Map::Tube::GraphViz->new(
        'callback_node' => \&node_color_without_label,
        'driver' => 'neato',
        'tube' => $obj,
);

# Get graph to file.
$g->graph('Nanjing.png');

# Print file.
system "ls -l Nanjing.png";

# Output like:

# Print out.
map { print encode_utf8($_->name)."\n"; } sort @{$lines_ar};

# Output:
