| :mod:`altgraph` --- A Python Graph Library |
| ================================================== |
| |
| .. module:: altgraph |
| :synopsis: A directional graph for python |
| |
| altgraph is a fork of `graphlib <http://pygraphlib.sourceforge.net>`_ tailored |
| to use newer Python 2.3+ features, including additional support used by the |
| py2app suite (modulegraph and macholib, specifically). |
| |
| altgraph is a python based graph (network) representation and manipulation package. |
| It has started out as an extension to the `graph_lib module <http://www.ece.arizona.edu/~denny/python_nest/graph_lib_1.0.1.html>`_ |
| written by Nathan Denny it has been significantly optimized and expanded. |
| |
| The :class:`altgraph.Graph.Graph` class is loosely modeled after the `LEDA <http://www.algorithmic-solutions.com/enleda.htm>`_ |
| (Library of Efficient Datatypes) representation. The library |
| includes methods for constructing graphs, BFS and DFS traversals, |
| topological sort, finding connected components, shortest paths as well as a number |
| graph statistics functions. The library can also visualize graphs |
| via `graphviz <http://www.research.att.com/sw/tools/graphviz/>`_. |
| |
| |
| .. exception:: GraphError |
| |
| Exception raised when methods are called with bad values of |
| an inconsistent state. |
