com.vividsolutions.jts.operation.overlay.validate.OverlayResultValidator

Validates that the result of an overlay operation is geometrically correct, within a determined tolerance. Uses fuzzy point location to find points which are definitely in either the interior or exterior of the result geometry, and compares these results with the expected ones.

This algorithm is only useful where the inputs are polygonal. This is a heuristic test, and may return false positive results (I.e. it may fail to detect an invalid result.) It should never return a false negative result, however (I.e. it should never report a valid result as invalid.) @author Martin Davis @version 1.7 @see OverlayOp

    return new GeometryResult(result);
  }
  
  private void validate(int opCode, Geometry g0, Geometry g1, Geometry result)
  {
    OverlayResultValidator validator = new OverlayResultValidator(g0, g1, result);
    // check if computed result is valid
    if (! validator.isValid(opCode)) {
      Coordinate invalidLoc = validator.getInvalidLocation();
      String msg = "Operation result is invalid [OverlayResultValidator] ( " + WKTWriter.toPoint(invalidLoc) + " )";
      reportError(msg);
    } 
  }
