com.vividsolutions.jts.geom.GeometryFactory.createPolygon()
Constructs a Polygon with the given exterior boundary and interior boundaries. @param shell the outer boundary of the new Polygon, or null or an empty LinearRing if the empty geometry is to be created. @param holes the inner boundaries of the new Polygon, or null or empty LinearRing s if the empty geometry is to be created.
