  • Method Details

    • reverseDirection

      public void reverseDirection()
      Method to reverse the upstream to downstream orientation of the stream element. The method reverses the order of points in the StreamPolyLine and reorients the node stream cordinates. Non-default stream stationing will remain intack, but default stream stationing will reverse direction. This may cause existing data sets that rely on the stream stationing to have problems, so use this method with care!!
