SYNOPSIS

        package foo;
        use Meta::Graph::Directed qw();
        my($object)=Meta::Graph::Directed->new();
        my($result)=$object->method();

DESCRIPTION

This class is here to provide a place to add method to the Graph::Directed module available from CPAN. I know that Graph::Directed looks pretty nice but still if I need any convenience methods or maybe a small algorithm or two it will be nice to add them at the graph level.

FUNCTIONS

        vertices_num($)
        edges_num($)
        get_single_succ($$)
        nodes_delete_all($)
        TEST($)

FUNCTION DOCUMENTATION

vertices_num($)

This method returns the number of vertices in the graph. It's true that the method vertices in Graph returns this number if called in a scalar context but I hate having methods behave differently in different contexes.

edges_num($)

This method returns the number of edges in the graph.

get_single_succ($$)

This method will retrieve the single successor node for a certain node (will make sure that it has only 1 of those).

nodes_delete_all($)

This method will delete all vertices and edges from the graph.

TEST($)

Test suite for this module. Currently it just constructs a graph and prints some statistics.
