Interface ICoordinateFilter

Namespace
NetTopologySuite.Geometries
Assembly
NetTopologySuite.dll

An interface for classes which use the values of the coordinates in a Geometry. Coordinate filters can be used to implement centroid and envelope computation, and many other functions.

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

Note: it is not recommended to use these filters to mutate the coordinates. There is no guarantee that the coordinate is the actual object stored in the source geometry. In particular, modified values may not be preserved if the source Geometry uses a non-default CoordinateSequence. If in-place mutation is required, use ICoordinateSequenceFilter. 
public interface ICoordinateFilter

Methods

Filter(Coordinate)

Performs an operation with the provided coord. Note that there is no guarantee that the input coordinate is the actual object stored in the source geometry, so changes to the coordinate object may not be persistent.

void Filter(Coordinate coord)

Parameters

coord Coordinate

A Coordinate to which the filter is applied.
