Interface ICoordinateFilter

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.

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.

Declaration

void Filter(Coordinate coord)

Parameters

Type	Name	Description
Coordinate	coord	A `Coordinate` to which the filter is applied.
