Re: [Jung-support] Starting Services - Directed Graph

[Andrew <su...@gm...>]

You suggested it wouldn't be difficult to write one using the API, so that's
what I was asking for some help with.

I ended up writing it myself.  Didn't take long, however, I found that what
I really need is weighted sort.  Does JUNG provide this (weighted sort of
directed graph), and if so could you point me to an example?  Thanks
