Class OffsetSegmentString

java.lang.Object
org.locationtech.jts.operation.buffer.OffsetSegmentString
class OffsetSegmentString extends Object
A dynamic list of the vertices in a constructed offset curve. Automatically removes adjacent vertices which are closer than a given tolerance.

  • Field Details

    • COORDINATE_ARRAY_TYPE

      private static final Coordinate[] COORDINATE_ARRAY_TYPE

    • ptList

      private ArrayList ptList

    • precisionModel

      private PrecisionModel precisionModel

    • minimimVertexDistance

      private double minimimVertexDistance
      The distance below which two adjacent points on the curve are considered to be coincident. This is chosen to be a small fraction of the offset distance.
