Hello Pankaj Malhotra, Yes, I need to assign more than values to the edge. I need the edge has [flow, capacity, distinction, source] You says I need to create a new class type for edge, How can I pass it to json class and how can I make json class read my new edge object.
I need to submit my code next week, so any answer or recommendation will definitely help. thanks Rana On Mar 24, 2014, at 7:29 AM, Pankaj Malhotra <pankajiit...@gmail.com> wrote: > If I get your point-1 right, you want to have a vertex class type other than > the ones available, for example: Text.
