NAME
Graph::Easy::As_graph6 - stringize Graph::Easy in graph6 format
SYNOPSIS
use Graph::Easy;
my $graph = Graph::Easy->new;
$graph->add_edge('foo','bar');
use Graph::Easy::As_graph6;
print $graph->as_graph6;DESCRIPTION
Graph::Easy::As_graph6 adds an as_graph6() method to Graph::Easy to give a graph as a string of graph6 format. This format is per
The format represents an undirected graph with no self-loops or multi-edges. Any self-loops in $graph are ignored. Multi-edges are written just once and if $graph is directed then an edge of either direction is written.
The format has no vertex names and no attributes. In the current implementation nodes are sorted alphabetically (sorted_nodes('name')) to give a consistent (though slightly arbitrary) vertex numbering.
See Graph::Graph6 for some notes on the format.
FUNCTIONS
The following new method is added to Graph::Easy.
$str = $graph->as_graph6 ()-
Return a string which is the graph6 representation of
$graph.The string returned includes a final newline
"\n"and so is suitable for writing directly to a file or similar.
