    • heuristic

      @Deprecated public boolean heuristic
      Deprecated.
      When set to true, the comparison uses a heuristic to speed it up. With this heuristic, for files with a constant small density of changes, the algorithm is linear in the file size.

    • no_discards

      @Deprecated public boolean no_discards
      Deprecated.
      When set to true, the algorithm returns a guaranteed minimal set of changes. This makes things slower, sometimes much slower.
