Class BufferDistanceValidator
java.lang.Object
com.vividsolutions.jts.operation.buffer.validate.BufferDistanceValidator
public class BufferDistanceValidator
- extends java.lang.Object
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.)

getErrorIndicator
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
