[jgrapht-users] BFS -- immediate predecessor across an edge?

[Nick W. <nic...@gm...>]

Hi

Using BreadthFirstIterator, how do I get the immediate predecessor/parent
vertex to the one I'm currently visiting? I can set up a client class
to listen for traversal events, but I can't see how to find the immediate
predecessor. (Note, I don't want to subclass BreadthFirstIterator to do
this).

TIA,
