Java api for nodes creation

[Ajay Singh]

Hi all
is there any java api for creation of topological nodes(star topology,bus topology) .Kindly provide pointers to the same

Thanks

What would such a software node do? The terms star and bus topology are most often used in the context of network setups.

[Ajay Singh]

More precisely, it would make a network topology displaying all the nodes and the relation ship between them.Like for ex four nodes is to be displayed A,B C,D.The diagram should display A is related to B with 0.6,B is related to D and C with 0.7 and 0.3 respectively,C is related to D with 0.1.So in the end a topological diagram is displayed with the nodes and relationship among them.

You mean something like a connected graph with nodes and edges? JGraph (on SourceForge) can do that, and there must be others like that out there.

thanks ulf for the response,also i would like to stretch/edit the nodes ,is that possible in JGraph?

also i would like to stretch/edit the nodes ,is that possible in JGraph?

Why not take a look (or at another JGraph) and see whether it does what you want? A sensible Google search would also lead you to some decent APIs.

The GEF (Graph Editing Framework) for Eclipse is another such framework which I have some experience with. GEF has some really quite good layout algorithms -- i.e., give it a complex graph, and it figures out a nice way to display it -- i.e., without crossing lines, etc, but also without any really ugly distortions. It does a good job.
