Interface CoordinateFilter

All Known Implementing Classes:
BufferCurveMaximumDistanceFinder.MaxPointDistanceFilter, CoordinateArrayFilter, CoordinateCountFilter, DiscreteHausdorffDistance.MaxPointDistanceFilter, UniqueCoordinateArrayFilter

public interface CoordinateFilter
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.

CoordinateFilter 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 CoordinateSequenceFilter.

      void filter(Coordinate coord)
      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.
      Parameters:
      coord - a Coordinate to which the filter is applied.
