    • extract

      public static Geometry extract(Geometry line, LinearLocation start, LinearLocation end)
      Computes the subline of a LineString between two LinearLocations on the line. If the start location is after the end location, the computed linear geometry has reverse orientation to the input line.
      Parameters:
      line - the line to use as the baseline
      start - the start location
      end - the end location
      Returns:
      the extracted subline

    • extract

      public Geometry extract(LinearLocation start, LinearLocation end)
      Extracts a subline of the input. If end invalid input: '<' start the linear geometry computed will be reversed.
      Parameters:
      start - the start location
      end - the end location
      Returns:
      a linear geometry

    • reverse

      private Geometry reverse(Geometry linear)

    • computeLine

      private LineString computeLine(LinearLocation start, LinearLocation end)
      Assumes input is valid (e.g. start invalid input: '<'= end)
      Parameters:
      start -
      end -
      Returns:
      a linear geometry

    • computeLinear

      private Geometry computeLinear(LinearLocation start, LinearLocation end)
      Assumes input is valid (e.g. start invalid input: '<'= end)
      Parameters:
      start -
      end -
      Returns:
      a linear geometry
