Hi to all!
I'm starting to work with geotools 2.5.5 and have a problem with the
path object which I get as result from the DijkstraShortestPathFinder.
According to this hint
http://n2.nabble.com/shortest-pth-display-td1937392.html#a1937392 I want
to display the shortest path as a join of linestrings. But if I try
this I failed because I get the the following cast exception:
java.lang.ClassCastException:
org.geotools.feature.simple.SimpleFeatureImpl cannot be cast to
com.vividsolutions.jts.geom.LineString
here is the relevant code snippet:
DijkstraShortestPathFinder pf = new DijkstraShortestPathFinder(graph,
source, weighter);
pf.calculate();
Path path = pf.getPath(dest);
LineString completeLineString = null;
boolean t = false;
for (Iterator itr = path.getEdges().iterator(); itr.hasNext();){
Edge e = (Edge) itr.next();
if (t == false) {
completeLineString = (LineString) e.getObject();
t = true;
} else {
GeometryUtil.joinLinestrings(completeLineString,
(LineString) e.getObject());
}
}
Could anyone help me in this regard please?
Thanks a lot!
Marcus
