      • 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.
