Subject Re: [graph] Why the Vertex and Edge interfaces?
Date Fri, 02 Mar 2012 07:50:14 GMT
Yeah, I would say something like this:

public interface Graph<V extends Serializable,E extends Serializable>
{
...
}

this is assuming you'd want to enforce the serialization stuff.
Otherwise it'd just be Graph<V,E>
