Detailed Description

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.

Constructor & Destructor Documentation

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

Parameters:
newFactory the GeometryFactory to create the edited Geometry with


Member Function Documentation

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.

Parameters:
geometry the Geometry to edit
operation the edit operation to carry out
Returns:
a new Geometry which is the result of the editing
