Questions about RMI

[<Nuno.Carvalho AT uk.fujitsu.com>]

Dear all,

 

I’m just started using GraphStream and I must say that this is a very powerful tool.

Now I want to use it with the RMI functionality. I want to implement the following scenario:

 

-          Process A is generating Nodes and Edges for the Graph

-          Process B is just getting the new nodes and edges and displaying it on the screen.

 

For that, I’ve been trying to follow this tutorial:

http://graphstream-project.org/doc/Tutorials/Using-remote-source_1.0/

 

So, before I had something like this:

 

Graph graph = new SingleGraph(“g”);

graph.display();

graph.addNode(...);

graph.addEdge(...);

// and so on...

 

Now I have this code split in two parts:

 

On one side, I have the part that displays the graph on the screen, which is very simple:

RMISource source = new RMISource();

Graph graph = new DefaultGraph(“g”);

source.addSink(graph);

graph.display();

 

 

On the other process, I must have an RMISink where I push the new nodes and edges, right?

So, I must have the following:

RMISink sink = new RMISink();

Sink.register(...);

 

Then, according to the Tutorial, I have to create a Generator, connect it to the Sink and start loop on the generator.nextEvents();

 

The questions that I have are the following:

-          The generator must be implemented by myself, based on my graph data source, or I can use some already implemented Generator with a interface similar to what I have for graphs(addNode, addEdge, etc)?

-          If I need to implement my own generator, how should I do it? Is there any tutorial to do this? I’m missing this part: how to add nodes and edges, and push it to the RMISink...

 

All help will be much appreciated!

 

Thanks and kind regards,

Nuno
