Map::Tube - Core library as Role (Moo) to process map data.
Version 3.09
The core module defined as Role (Moo) to process the map data. It provides the the interface to find the shortest route in terms of stoppage between two nodes. Also you can get all possible routes between two given nodes.
This role has been taken by the following modules (and many more):
Map::Tube::London
Map::Tube::Tokyo
Map::Tube::NYC
Map::Tube::Delhi
Map::Tube::Barcelona
Map::Tube::Prague
Map::Tube::Warsaw
Map::Tube::Sofia
Map::Tube::Berlin
use strict; use warnings; use Map::Tube::London; my $tube = Map::Tube::London->new; print $tube->get_shortest_route('Baker Street', 'Euston Square'), "\n";
You should expect the result like below:
Baker Street (Circle, Hammersmith & City, Bakerloo, Metropolitan, Jubilee), Great Portland Street (Circle, Hammersmith & City, Metropolitan), Euston Square (Circle, Hammersmith & City, Metropolitan)
use strict; use warnings; use Map::Tube::London; my $tube = Map::Tube::London->new; print $tube->get_shortest_route('Baker Street', 'Euston Square')->preferred, "\n";
You should now expect the result like below:
Baker Street (Circle, Hammersmith & City, Metropolitan), Great Portland Street (Circle, Hammersmith & City, Metropolitan), Euston Square (Circle, Hammersmith & City, Metropolitan)
It expects $from and $to station name, required param. It returns an object of type Map::Tube::Route. On error it throws exception of type Map::Tube::Exception.
$from
$to
It expects $from and $to station name, required param. It returns ref to a list of objects of type Map::Tube::Route. On error it throws exception of type Map::Tube::Exception.
Be carefull when using against a large map. You may encounter warning similar to as shown below when run against London map.
Deep recursion on subroutine "Map::Tube::_get_all_routes"
However for comparatively smaller map, like below,it is happy to give all routes.
A(1) ---- B(2) / \ C(3) -------- F(6) --- G(7) ---- H(8) \ / D(4) ---- E(5)
Returns map name.
Returns an object of type Map::Tube::Node.
Returns a list of object(s) of type Map::Tube::Node matching node name $node_name.
$node_name
Returns an object of type Map::Tube::Line.
Returns ref to a list of objects of type Map::Tube::Line.
Returns ref to a list of objects of type Map::Tube::Node for the $line_name.
$line_name
The Map::Tube::Plugin::Graph plugin add the support to generate the entire map or map for a particular line as base64 encoded string (png image).
Please refer to the documentation for more details.
The Map::Tube::Plugin::Formatter plugin adds the support to format the object supported by the plugin.
Please refer to the documentation for more info.
Gisbert W. Selke, built the add-on for Map::Tube to find stations and lines by name, possibly partly or inexactly specified. The module is a Moo role which gets plugged into the Map::Tube::* family automatically once it is installed.
The package Test::Map::Tube can easily be used to validate raw map data.Anyone building a new map using Map::Tube is advised to have a unit test as a part of their distribution.Just like in Map::Tube::London package,there is a unit test something like below:
use strict; use warnings; use Test::More; use Map::Tube::London; eval "use Test::Map::Tube"; plan skip_all => "Test::Map::Tube required" if $@; ok_map(Map::Tube::London->new);
The package Test::Map::Tube v0.09 or above can easily be used to validate map basic functions provided by Map::Tube.
use strict; use warnings; use Test::More; my $min_ver = 0.09; eval "use Test::Map::Tube $min_ver"; plan skip_all => "Test::Map::Tube $min_ver required" if $@; use Map::Tube::London; ok_map_functions(Map::Tube::London->new);
