I use jgrapht library in Java to create some graphs. I want to iterate through the existing vertices(that I have created in a previous state of the program) and add the corresponding edges depending on some criteria(if statements). As it seems to me the only way to add edges is:
DefaultWeightedEdge e1 = exampleGraph.addEdge("1", "2");
exampleGraph.setEdgeWeight(e1, 20.0);
From my point of view, this won't work in a for loop because it will always refer and change the same object. Any ideas?
for loop
{
exampleGraph.setEdgeWeight(exampleGraph.addEdge(x, y), w);
}
Did you try something like this?
