  public NodingFunctions()
Method Details
- snapRoundWithPointwisePrecisionReduction
  
  public static Geometry snapRoundWithPointwisePrecisionReduction(Geometry geom, double scaleFactor)
  
  Reduces precision pointwise, then snap-rounds. Note that output set may not contain non-unique linework (and thus cannot be used as input to Polygonizer directly). UnaryUnion is one way to make the linework unique.
  
  Parameters:
  
  geom - a geometry containing linework to node
  
  scaleFactor - the precision model scale factor to use
  
  Returns:
  
  the noded, snap-rounded linework
- isNodingValid
  
  public static boolean isNodingValid(Geometry geom)
- findSingleNodePoint
  
  public static Geometry findSingleNodePoint(Geometry geom)
- findNodePoints
  
  public static Geometry findNodePoints(Geometry geom)
- interiorIntersectionCount
  
  public static int interiorIntersectionCount(Geometry geom)
- MCIndexNodingWithPrecision
  
  public static Geometry MCIndexNodingWithPrecision(Geometry geom, double scaleFactor)
- MCIndexNoding
  
  public static Geometry MCIndexNoding(Geometry geom)
- scaledNoding
  
  public static Geometry scaledNoding(Geometry geom, double scaleFactor)
  
  Runs a ScaledNoder on input. Input vertices should be rounded to precision model.
  
  Parameters:
  
  geom -
  
  scaleFactor -
  
  Returns:
  
  the noded geometry
- createSegmentStrings
  
  private static List createSegmentStrings(Geometry geom)
