Re: [Rails-devel] Question regarding existence of routes

Here's what I ended up with so far:
compA is the private investor
compB is the company to check to see if there is a connection with
PublicCompanyI compA = operatingCompany.get();
...
NetworkGraphBuilder nwGraph =
NetworkGraphBuilder.create(gameManager);
NetworkCompanyGraph companyGraph =
NetworkCompanyGraph.create(nwGraph, compA);
SimpleGraph<NetworkVertex, NetworkEdge> graph =
companyGraph.createRouteGraph(true);
Set<NetworkVertex> verticies = graph.vertexSet();
...
for (TokenI token : compB.getTokens()) {
TokenHolder holder = token.getHolder();
if (!(holder instanceof Stop)) continue;
Stop city = (Stop) holder;
Station station = city.getRelatedStation();
for (NetworkVertex vert : verticies) {
if (vert.getType() == NetworkVertex.VertexType.STATION)
{
Station vertStation = vert.getStation();
if (station == vertStation) {
// There is a link between the companies!
Hooray!
}
}
}
}
...
This seems to work for simple cases, however, I suspect (without digging
too much) that it will get blocked by tokens, which I can't have. I bet it
won't be too hard to fix, tho.
