[Netron-graphlib] GraphML

[Martin C. <mar...@ei...>]

Hi Francois,

I'm getting there on the GraphML, I've only concentrated on serializing 
the info for the moment, but with the approach I've taken I don't think 
deserialization will be too difficult. Problem with XML/GraphML is 
everything has to be text, lots of ToString() on fields/properties 
(which may need to be overridden).

I wanted to run my implementation by you, before I go any further. Here 
goes:

I've created a new Attribute in the Netron.Graphlib.Attributes namespace 
called GraphMLData, which is used to tag all Properties that need to be 
persisted. As I walk the GraphAbstract collections I pass the objects to 
a static member function of the GraphMLDataAttribute which builds the 
key/data pairs necessary for GraphML.

Mmmm... It's kind of difficult to explain in an email. Can I send you 
the code? I can put it into CVS as everything compiles and so far as I 
can tell works ok. There are quite a few new supporting classes added 
into the Netron.Graphlib.IO namespace.

To use the Serialization you only need a few lines of code in your app:

XmlTextWriter tw = new XmlTextWriter("MyFile.xml",Encoding.Unicode);
GraphMLSerializer g = new GraphMLSerializer();
g.Serialize(tw,graphControl1.Abstract);
tw.Close();

I'll be on IM this evening if you want to chat.

Look forward to your reply.

Regards,

Martin
