Class GeometryCombiner

Namespace

NetTopologySuite.Geometries.Utilities

Assembly

NetTopologySuite.dll

Combines Geometrys to produce a GeometryCollection of the most appropriate type.

public class GeometryCombiner

Inheritance

object

GeometryCombiner

Inherited Members

object.GetType()

object.MemberwiseClone()

object.ToString()

object.Equals(object)

object.Equals(object, object)

object.ReferenceEquals(object, object)

object.GetHashCode()

Remarks

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 IPolygonal geometries are combined and result in a self-intersection).

Constructors

GeometryCombiner(IEnumerable<Geometry>)

Creates a new combiner for a collection of geometries

public GeometryCombiner(IEnumerable<Geometry> geoms)

Parameters

geoms IEnumerable<Geometry>

The geometries to combine
