Class 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 or null if no error was found
