GOBLIN Graph Library 2.8b26 (Default branch)
Image The GOBLIN project consists of a C++ class library for a large series of graph optimization problems, GOSH, an extension of the Tcl/Tk scripting language to graph objects, and GOBLET, a graphical user interface to the library functions. GOBLET includes a graph editor and supports the standard graph layout methods. License: GNU Lesser General Public License (LGPL) Changes:
The Tcl API has been completely revised to conform with the method names in the C++ core library. Tcl commands now consistently support optional parameters. The HTML reference now covers all graph methods in the Tcl API. A constructor method for k-ary (cyclic) butterfly graphs has been added. Image

graph::reader::xml

Graph::Reader::XML(3pm) 				User Contributed Perl Documentation				   Graph::Reader::XML(3pm)

NAME

       Graph::Reader::XML - class for reading a Graph instance from XML

SYNOPSIS

	 use Graph::Reader::XML;
	 use Graph;

	 $reader = Graph::Reader::XML->new();
	 $graph = $reader->read_graph('mygraph.xml');

DESCRIPTION

       Graph::Reader::XML is a perl class used to read a directed graph stored as XML, and return an instance of the Graph class.

       The XML format is designed to support the Graph classes: it can be used to represent a single graph with a collection of nodes, and edges
       between those nodes.  The graph, nodes, and edges can all have attributes specified,

       Graph::Reader::XML is a subclass of Graph::Reader, which defines the generic interface for Graph reader classes.

METHODS

   new()
       Constructor - generate a new reader instance.

	 $reader = Graph::Reader::XML->new();

       This doesn't take any arguments.

   read_graph()
       Read a graph from a file:

	 $graph = $reader->read_graph( $file );

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

KNOWN BUGS

       Attribute values must be scalar. If they're not, well, you're on your own.
