Method Detail
- transformCoordinates
```
protected CoordinateSequence transformCoordinates(CoordinateSequence coords,

```
  Description copied from class: GeometryTransformer
  
  Transforms a CoordinateSequence. This method should always return a valid coordinate list for the desired result type. (E.g. a coordinate list for a LineString must have 0 or at least 2 points). If this is not possible, return an empty sequence - this will be pruned out.
  
  Overrides:
  
  transformCoordinates in class GeometryTransformer
  
  Parameters:
  
  coords - the coordinates to transform
  
  parent - the parent geometry
  
  Returns:
  
  the transformed coordinates
- snapLine
```
private Coordinate[] snapLine(Coordinate[] srcPts,
                              Coordinate[] snapPts)
