java.lang.Objectorg.jgrapht.ext.GmlExporter<V,E>
public class GmlExporter<V,E>
Exports a graph into a GML file (Graph Modelling Language).
For a description of the format see http://www.infosun.fmi.uni-passau.de/Graphlet/GML/.
The objects associated with vertices and edges are exported as labels
using their toString() implementation. See the setPrintLabels(Integer)
method. The default behavior is to export no label
information.
