Graph::Maker(3pm)

NAME

Graph::Maker - Create many types of graphs

VERSION

Version 0.02

SYNOPSIS

Base class for Graph::Maker::*. Subclasses extend this class and override the init method. The init method is passed the class and the parameters. This uses Class::Factory.

        use strict;
        use warnings;
        use Graph;
        use Graph::Maker;
        use Graph::Maker::Linear; # or import qw/Graph::Maker/;
        my $g = new Graph::Maker('linear', N => 10);
        # work with the graph

SUBCLASSING

The simplest example is the linear graph, nodes i is connected to node i+1. The implimentation can simply be:

        package Graph::Maker::Linear;
        use strict;
        use warnings;
        use Carp;
        use base qw/Graph::Maker/;
        use Graph;
        sub init
        {
                my ($self, %params) = @_;
                my $N = delete($params{N});
                my $g = new Graph(%params);
                $g->add_path(1..$N);
                return $g;
        }
        Graph::Maker->add_factory_type( 'linear' => __PACKAGE__ );
        1;

A real implimentation should check that N is defined and is valid (the one provided in this package does). It is that simple.

ACKNOWLEDGEMENTS

This package owes a lot to NetworkX <http://networkx.lanl.gov/>, this is something I think is really needed to extend the great Graph module.
