Hi Peter,
Any hint how I get the QueryResult in the calcWeight?
So far I was using:
public class MyWeighting extends PriorityWeighting {
...
@Override
public double calcWeight( EdgeIteratorState edgeState, boolean reverse, int
prevOrNextEdgeId )
{
double weight = super.calcWeight(edgeState, reverse, prevOrNextEdgeId);
if (Double.isInfinite(weight))
return Double.POSITIVE_INFINITY;
double tempWeight =weight / (0.5
+encoder.getDouble(edgeState.getFlags(), KEY));
int calcEdge=edgeState.getEdge();
if(myWeightList.containsKey(calcEdge)) {
//do some calculation
return (myWeight!=0 ? tempWeight*myWeight : tempWeight);
}
else
return tempWeight;
for the creation of myWeightList I'm use
QueryResult myQR = index.findClosest(tmpPoint.getLat(),tmpPoint.getLon(),
EdgeFilter.ALL_EDGES);
in a different class.
I could use for calcEdge the findClosest() with
edgeState.fetchWayGeometry.getLat/getLon and create a QueryResult
but I guess that is not the way to go.
btw I forgot to mention I'm using Graphhopper 4.0.0, if that is important.
thx Markus
