# dupeGuru 4.0.4 documentation

## core.results

class `core.results.``Results`(app)

  Manages a collection of duplicate `Group`.

  This class takes care or marking, sorting and filtering duplicate groups.

  `groups`

    The list of `Group` contained managed by this instance.

  `dupes`

    A list of all duplicates (`File` instances), without ref, contained in the currently managed `groups`.

  `apply_filter`(filter_str)

    Applies a filter `filter_str` to `groups`

    When you apply the filter, only dupes with the filename matching `filter_str` will be in in the results. To cancel the filter, just call apply_filter with `filter_str` to None, and the results will go back to normal.

    If call apply_filter on a filtered results, the filter will be applied on the filtered results.

    Parameters

      filter_str (str) – a string containing a regexp to filter dupes with.

  `get_group_of_duplicate`(dupe)

    Returns `Group` in which `dupe` belongs.

  `load_from_xml`(infile, get_file, j=<hscommon.jobprogress.job.NullJob object>)

    Load results from `infile`.

    Parameters

      - infile – a file or path pointing to an XML file created with `save_to_xml()`.

      - get_file – a function f(path) returning a `File` wrapping the path.

      - j – A job progress instance.

  `make_ref`(dupe)

    Make `dupe` take the `ref` position of its group.

  `perform_on_marked`(func, remove_from_results)

    Performs `func` on all marked dupes.

    If an `EnvironmentError` is raised during the call, the problematic dupe is added to self.problems.

    Parameters

      remove_from_results (bool) – If true, dupes which had `func` applied and didn’t cause any problem.

  `remove_duplicates`(dupes)

    Remove `dupes` from their respective `Group`.

    Also, remove the group from `groups` if it ends up empty.

  `save_to_xml`(outfile)

    Save results to `outfile` in XML.

    Parameters

      outfile – file object or path.

  `sort_dupes`(key, asc=True, delta=False)

    Sort `dupes` according to `key`.

    Parameters

      - key (str) – key attribute name to sort with.

      - asc (bool) – If false, sorting is reversed.

      - delta (bool) – If true, sorting occurs using delta values.

  `sort_groups`(key, asc=True)

    Sort `groups` according to `key`.

    The `ref` of each group is used to extract values for sorting.

    Parameters

      - key (str) – key attribute name to sort with.

      - asc (bool) – If false, sorting is reversed.
