                             Shape shape,
                             EdgeFilter filter)

This method fills the edgeIds hash with edgeIds found inside the specified shape

fillEdgeIDs

public void fillEdgeIDs(GHIntHashSet edgeIds,
                        org.locationtech.jts.geom.Geometry geometry,
                        EdgeFilter filter)
