Method Detail

edit

public final Geometry edit(Geometry geometry,
                           GeometryFactory targetFactory)

Description copied from interface: GeometryEditorEx.GeometryEditorOperation

Edits a Geometry by returning a new Geometry with a modification. The returned geometry may be:

• the input geometry itself The returned Geometry might be the same as the Geometry passed in. It may be null if the geometry is to be deleted.

Specified by:

edit in interface GeometryEditorEx.GeometryEditorOperation

Parameters:

geometry - the Geometry to modify

Returns:

a new Geometry which is a modification of the input Geometry

edit

public abstract Coordinate[] edit(Coordinate[] coordinates,
                                  Geometry geometry)

Edits the array of Coordinates from a Geometry.

If it is desired to preserve the immutability of Geometrys, if the coordinates are changed a new array should be created and returned.

Parameters:

coordinates - the coordinate array to operate on

geometry - the geometry containing the coordinate list

Returns:

an edited coordinate array (which may be the same as the input)
