EMF Compare/API Viewer FilteringGrouping

The API has to allow to launch a graphical comparison of models, specifying the filters to activate and the grouping configuration to use.

It is the service class: CompareServices which contains this API:

• void openView(final ComparisonSnapshot input, final List<IDifferenceFilter> filters, final IDifferenceGroupingFacility group)

It enables to open the structure view from a comparion result (snapshot) with a given filtering and grouping configuration.

Here is an exemple to call this method:

---

final List<IDifferenceFilter> filters = DifferenceFilterRegistry.INSTANCE.getFilters(DifferenceFilterRegistry.FILTERING_ADDED_ELEMENTS_ID);

final ISelectionProvider provider = editor.getEditorSite().getSelectionProvider();

if (provider instanceof IInputProvider) {

  final Object root = ((IInputProvider)provider).getInput();

  if (root instanceof ComparisonSnapshot) {

    CompareServices.openView((ComparisonSnapshot)root, filters, null);

  }

}
