Interface IGeometryComponentFilter

Geometry classes support the concept of applying an IGeometryComponentFilter filter to a geometry.

Namespace: NetTopologySuite.Geometries

Assembly: NetTopologySuite.dll

Syntax

public interface IGeometryComponentFilter

Remarks

The filter is applied to every component of a geometry as well as to the geometry itself. For instance, in a Polygon, all the LinearRing components for the shell and holes are visited, as well as the polygon itself. In order to process only atomic components, the Filter(Geometry) method code must explicitly handle only LineStrings, LinearRings and Points.

An IGeometryComponentFilter filter can either record information about the Geometry or change the Geometry in some way.

IGeometryComponentFilter is an example of the Gang-of-Four Visitor pattern.

Methods

Filter(Geometry)

Performs an operation with or on a geometry component.

Declaration

void Filter(Geometry geom)

Parameters

Type	Name	Description
Geometry	geom	A component of the geometry to which the filter is applied.
