Re: [jgrapht-users] Extending Default Edge

[Ricardo R. <ric...@gm...>]

Hi,

>From the sample in project page:
http://nlp.stanford.edu/software/lex-parser.shtml#Sample

<http://nlp.stanford.edu/software/lex-parser.shtml#Sample>I imagine the
TypedDependencies are:
det(rain-3, The-1)
amod(rain-3, strongest-2)
nsubj(shut-8, rain-3)
...

And, by dependecy relations, I understand: det, amod, nsubj, etc..

So... if that's the case, you don't need to use the class DefaultEdge as a
type for your edges or extend it, JGraphT is based on Generics... so you can
use whatever class which is suitable for you...
E.g.:

SimpleGraph<String, String> graph = new SimpleGraph<String,
String>(String.class);

So you can add edges with the desired information:
graph.addEdge("rain-3", "The-1", "det");
graph.addEdge("rain-3", "strongest-2", "amod");
graph.addEdge("shut-8", "rain-3", "nsubj");

Probably your vertices and edges are not String's, so you just have to
choose the right class for your graphs...
I hope I could help you.
