Class BufferDistanceValidator

Hierarchy: Object , BufferDistanceValidator

public class BufferDistanceValidator

Validates that a given buffer curve lies an appropriate distance from the input generating it. Useful only for round buffers (cap and join). Can be used for either positive or negative distances.

This is a heuristic test, and may return false positive results (I.e. it may fail to detect an invalid result.) It should never return a false negative result, however (I.e. it should never report a valid result as invalid.)

public BufferDistanceValidator(Geometry input, double bufDistance, Geometry result)

public boolean isValid()

public String getErrorMessage()

public Coordinate getErrorLocation()

public Geometry getErrorIndicator()

Gets a geometry which indicates the location and nature of a validation failure.

The indicator is a line segment showing the location and size of the distance discrepancy.

Returns:: a geometric error indicator or null if no error was found
