        public QueryBasedFeatureSettingDelegate​(org.eclipse.emf.ecore.EStructuralFeature eStructuralFeature,

                                                boolean dynamicEMFMode)
        Constructs a new QueryBasedFeatureSettingDelegate instance based on the given parameters. The scope of the VIATRA Query engine in this case will be the one provided by QueryBasedFeatureHelper#prepareNotifierForSource(InternalEObject).
        Parameters:
        eStructuralFeature - the parent structural feature of the setting delegate
        factory - the factory used to create VIATRA Query engine for the setting delegate
        querySpecification - the query specification used for the evaluation of the setting delegate
        dynamicEMFMode - indicates whether the engine should be created in dynamic EMF mode

        Parameters:
        eStructuralFeature - the parent structural feature of the setting delegate
        factory - the factory used to create VIATRA Query engine for the setting delegate
        querySpecification - the query specification used for the evaluation of the setting delegate
        isResourceScope - indicates whether the Resource of the InternalEObject is enough as a scope during the evaluation of the setting delegate
        dynamicEMFMode - indicates whether the engine should be created in dynamic EMF mode

      • initializeSettingDelegate

        public void initializeSettingDelegate​(org.eclipse.emf.common.notify.Notifier rootNotifier)
        Initializes the query based feature setting delegate using the given notifier as the root of the query engine base index. This is usually the ResourceSet unless you know what you are doing.
        Parameters:
        rootNotifier - the root of the indexing for the matcher driving the feature
