[jgrapht-users] request for general edges

[Hans-Martin A. <dr...@go...>]

Folks,

today I explored JGraphT. The design allows me to use any Vertex object that
pleases me. I chose to define a class Vertex as

public class Vertex<V> {
    private final V payload;
    public Vertex(V payload) {
        this.payload = payload;
    }
    public V getObject() {
        return payload;
    }
    @Override
    public String toString() {
        return payload.toString();
    }
}

I would like to do the same for the edge. However, the design of JGraphT
does not permit a design where I have full control over the edge. I consider
this to be a design flaw. I should like to be able to use an edge that has a
name, or in general a payload object.

This could be achieved, if there were a method

graph.addEdge(Edge edge)

Edge would have to be an interface with two methods getSource() und
getTarget().

Is there anything that stands in the way of such a design change? Why does
JGraphT have to have control over the constructor of my edge?

Thanks.
