Graph::Writer::VCG(3) User Contributed Perl DocumentationGraph::Writer::VCG(3)

NAME
       Graph::Writer::VCG - write out directed graph in	VCG format

SYNOPSIS
	 use Graph;
	 use Graph::Writer::VCG;

	 $graph	= Graph->new();
	 # add edges and nodes to the graph

	 $writer = Graph::Writer::VCG->new();
	 $writer->write_graph($graph, 'mygraph.vcg');

DESCRIPTION
       Graph::Writer::VCG is a class for writing out a directed	graph in the
       file format used	by the VCG tool, originally developed for Visualising
       Compiler	Graphs.	 The graph must	be an instance of the Graph class,
       which is	actually a set of classes developed by Jarkko Hietaniemi.

       If you have defined any attributes for the graph, nodes,	or edges, they
       will be written out to the file,	as long	as they	are attributes
       understood by VCG.

METHODS
   new()
       Constructor - generate a	new writer instance.

	 $writer = Graph::Writer::VCG->new();

       This doesn't take any arguments.

   write_graph()
       Write a specific	graph to a named file:

	 $writer->write_graph($graph, $file);

       The $file argument can either be	a filename, or a filehandle for	a
       previously opened file.

KNOWN BUGS AND LIMITATIONS
       o   Attributes with non-atomic values aren't currently handled.	This
	   includes the	loc, classname,	colorentry, and	infoname attributes
	   for graphs, and the loc attribute for nodes,

       o   Can currently only handle graph, node, and edge elements and	their
	   attributes.	So doesn't know	about foldnode_defaults	and things
	   like	that.
