checkSplitEdgesCorrectness method

void checkSplitEdgesCorrectness(List splitEdges)

Checks the correctness of the set of split edges corresponding to this edge.

@param splitEdges the split edges for this edge (in order)

Implementation

void checkSplitEdgesCorrectness(List splitEdges) {
  List<Coordinate> edgePts = edge.getCoordinates();

  // check that first and last points of split edges are same as endpoints of edge
  SegmentString split0 = splitEdges[0];
  Coordinate pt0 = split0.getCoordinate(0);
  if (!pt0.equals2D(edgePts[0]))
    throw new RuntimeException(
        "bad split edge start point at " + pt0.toString());

  SegmentString splitn = splitEdges[splitEdges.length - 1];
  List<Coordinate> splitnPts = splitn.getCoordinates();
  Coordinate ptn = splitnPts[splitnPts.length - 1];
  if (!ptn.equals2D(edgePts[edgePts.length - 1]))
    throw new RuntimeException(
        "bad split edge end point at " + ptn.toString());
