Usage

Reading and writing of DOT files is done via DOTMarshaller

Reading DOT

Graph g = DOTMarshaller.importGraph(inputStream);

Writing DOT

Graph g = new Graph(false, GraphType.digraph, "mygraph");
Node n1 = new Node("n1");
g.addNode(n1);
Node n2 = new Node("node2");
g.addNode(n2);
Edge theEdge = new Edge("n1", "node2");
g.addEdge(theEdge);
DOTMarshaller.exportGraph(g, baos);

Creates:

digraph mygraph {
   node2;
   n1;
   n1 -> node2;
}
