    • constructSegmentWKT

      protected void constructSegmentWKT​(int currentSegment, byte segment, int pointEndIndex)
      Constructs a Segment in WKT form. SQL Server re-uses the last point of a segment if the following segment is of type 3 (first arc) or type 2 (first line). This makes sense because the last point of a segment and the first point of the next segment have to match for a valid curve. This means that the code has to look ahead and decide to decrement the currentPointIndex depending on what segment comes next, since it may have been reused (and it's reflected in the array of points)
      Parameters:
      currentSegment - .
      segment - .
      pointEndIndex - .

    • constructGeometryCollectionWKT
