Constructor Detail

QueryBasedFeatureSettingDelegate

public QueryBasedFeatureSettingDelegate(org.eclipse.emf.ecore.EStructuralFeature eStructuralFeature,
                                        QueryBasedFeatureSettingDelegateFactory factory,
                                        IQuerySpecification<Matcher> querySpecification,
                                        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({@link 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

QueryBasedFeatureSettingDelegate

public QueryBasedFeatureSettingDelegate(org.eclipse.emf.ecore.EStructuralFeature eStructuralFeature,
                                        QueryBasedFeatureSettingDelegateFactory factory,
                                        IQuerySpecification<Matcher> querySpecification,
                                        boolean isResourceScope,
                                        boolean dynamicEMFMode)

Constructs a new QueryBasedFeatureSettingDelegate instance based on the given parameters.

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

Method Detail

get

protected java.lang.Object get(org.eclipse.emf.ecore.InternalEObject owner,
                               boolean resolve,
                               boolean coreType)

Specified by:

get in class org.eclipse.emf.ecore.util.BasicSettingDelegate.Stateless

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

Since:

1.3

isSet

protected boolean isSet(org.eclipse.emf.ecore.InternalEObject owner)

Specified by:

isSet in class org.eclipse.emf.ecore.util.BasicSettingDelegate.Stateless
