      hasGap - true if there are gaps

    • hasGap

      boolean hasGap()
      Returns true if the segment has a gap.
      Returns:
      true if the segment has a gap

    • setOverlapping

      void setOverlapping(boolean isOverlapping)
      Set the isOverlapping property indicating that some segments may be overlapping.
