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 example 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); } }
The API can be called from an existing opened EMF Compare editor:
void openView(IEditorPart editor, final List<IDifferenceFilter> filters, final IDifferenceGroupingFacility group)
Here is an example to call this method:
IEditorPart editor = null; final IWorkbench workbench = PlatformUI.getWorkbench(); if (workbench != null) { final IWorkbenchWindow workbenchWindow = workbench.getActiveWorkbenchWindow(); if (workbenchWindow != null) { final IWorkbenchPage page = workbenchWindow.getActivePage(); if (page != null) { final IEditorReference[] editors = page.getEditorReferences(); for (IEditorReference iEditorReference : editors) { if (editorInput.equals(iEditorReference.getEditorInput())) { editor = iEditorReference.getEditor(true); break; } } } } } CompareServices.openView(editor, null, null);
These last methods can be called without filtering and grouping configuration. It is equivalent to put filters and group to null value.

void openView(IEditorPart editor)
