Interface IGeometryComponentFilter

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

Namespace: NetTopologySuite.Geometries

Assembly: NetTopologySuite.dll

Syntax

public interface IGeometryComponentFilter

Remarks

The filter is applied to every component of the Geometry which is itself a Geometry and which does not itself contain any components. (For instance, all the LinearRings in Polygons are visited, but in a MultiPolygon the Polygons themselves are not visited.) Thus the only classes of Geometry which must be handled as arguments to Filter(Geometry) are 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 geom.

Declaration

void Filter(Geometry geom)

Parameters

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