Class GeometryCombiner

Hierarchy: Object , GeometryCombiner

public class GeometryCombiner

Combines Geometrys to produce a GeometryCollection of the most appropriate type. Input geometries which are already collections will have their elements extracted first. No validation of the result geometry is performed. (The only case where invalidity is possible is where Polygonal geometries are combined and result in a self-intersection).
