GeometryEditor ()  
GeometryEditor (const GeometryFactory *newFactory)  
std::unique_ptr< Geometry >  edit (const Geometry *geometry, GeometryEditorOperation *operation) 
Supports creating a new Geometry which is a modification of an existing one. Geometry objects are intended to be treated as immutable. This class allows you to "modify" a Geometry by traversing it and creating a new Geometry with the same overall structure but possibly modified components.
The following kinds of modifications can be made:
Note that all changes must be consistent with the original Geometry's structure (e.g. a Polygon cannot be collapsed into a LineString).
The resulting Geometry is not checked for validity. If validity needs to be enforced, the new Geometry's isValid should be checked.
geos::geom::util::GeometryEditor::GeometryEditor  (  ) 
Creates a new GeometryEditor object which will create an edited Geometry with the same GeometryFactory as the input Geometry.
geos::geom::util::GeometryEditor::GeometryEditor  (  const GeometryFactory *  newFactory  ) 
Creates a new GeometryEditor object which will create the edited Geometry with the given GeometryFactory
newFactory  the GeometryFactory to create the edited Geometry with 
std::unique_ptr<Geometry> geos::geom::util::GeometryEditor::edit  (  const Geometry *  geometry, 
GeometryEditorOperation *  operation  
) 
Edit the input Geometry with the given edit operation. Clients will create subclasses of GeometryEditorOperation or CoordinateOperation to perform required modifications.
