How to store Graph in a text file using Graphstream

Question

I know how to handle graphs using matrices and linked list. I am new to Graphstream. I want to know is there any in-built function in Graphstream in java to store/Read Graph type graphs in text files and what is the format of storing such graphs in a file?

Answer 1

Reading files using FileSource lists the file formats supported by concrete implementations of FileSource. It outlines the use of readAll(), as well as reading event-by-event from certain formats.

• DGS (GraphStream)
• DOT (GraphViz)
• GML
• TLP (Tulip)
• NET (Pajek)
• GraphML
• GEXF (Gephi)

In particular, The DGS File Format Specification describes DGS, the default GraphStream text file format. In outline, a FileSource connects a file to a graph:

Graph g = …;
FileSource fs = …;
fs.addSink(g);
fs.readAll(…);

Can I get some sample DGS file online storing big Graph?

Some small examples are shown here; a large example of the road network of Le Havre, France is cited here.
