METHODS

init()

This is the core method of the module, where we actually define the relationship among the diffrerent nodes. I have taken extra care to depict the relationship. However I would be more than happy to receieve any suggestion to improve the logic. Please note "Transport for London" is the owner of the data used here.

use strict; use warnings;
use Map::Tube::Node;

use strict; use warnings;
# Loads up the default node mapping definitions.
my $node = Map::Tube::Node::init();

load_element()

This loads all the nodes defined. Currently covers Bakerloo, Central, Circle, District, Hammersmith & City, Jubilee, Metropolitan, Northern, Piccadilly and Victoria. I shall be finishing the last remaining Waterloo & City line very soon. Please note this is still very experimental in nature.

use strict; use warnings;
use Map::Tube::Node;

# Loads all the node definitions.
my $element = Map::Tube::Node::load_element();

load_line()

This loads all the tube lines with their node code.

use strict; use warnings;
use Map::Tube::Node;

# Loads all the node codes with the tube lines information.
my $line = Map::Tube::Node::load_line();

upcase_element_name

This loads all the nodes with name in uppercase. This is to allow case-insensitive name lookup. User can also provide the node list otherwise it will pick the default list.

use strict; use warnings;
use Map::Tube::Node;

# Returns a new list of element with names in upper case.
my $upcase = Map::Tube::Node::upcase_element_name();
