code: public void addSubPath(Coordinate[] coordinates, boolean closed) {
  		subPaths.add(new SubPath(coordinates, closed));
  		updateCoordinates();
  
  	}
docs: Add a new sub-path to the path. A path can have multiple sub-paths. Sub-paths may be disconnected lines or rings
  but, thanks to even-odd rule, holes can be added as well.
