Constructor Detail

NotifiableIdEObjectCollectionImpl

public NotifiableIdEObjectCollectionImpl(org.eclipse.emf.ecore.xmi.XMIResource xmiResource)
                                  throws IOException

Constructor. Adds the contents of the given XMIResource as model elements to the collection. If the XMIResource also has XMI IDs assigned to the EObjects it contains, they will be used for creating the model element IDs within the project, if not, the model element IDs will get created on the fly. An EObjectChangeNotifier is also attached to the given XMIResource.

Parameters:

xmiResource - a XMIResource

Throws:

IOException - if the given XMIResource could not be loaded

Method Detail

modelElementAdded

public void modelElementAdded(IdEObjectCollection collection,
                              org.eclipse.emf.ecore.EObject eObject)

Called when the eObject has been added to the collection.

Specified by:

modelElementAdded in interface IdEObjectCollectionChangeObserver

Parameters:

collection - the IdEObjectCollection to which the eObject was added

eObject - the EObject that has been added to the collection

See Also:

IdEObjectCollectionChangeObserver.modelElementAdded(org.eclipse.emf.emfstore.internal.common.model.IdEObjectCollection, org.eclipse.emf.ecore.EObject)

addCutElement

public abstract void addCutElement(org.eclipse.emf.ecore.EObject eObject)

Add a new cut element.

Parameters:

eObject - The new cut element.

initMapping

public void initMapping()

Description copied from class: IdEObjectCollectionImpl

Initializes the ID caches of the collection, i.e. the collection will call IdEObjectCollection.getModelElements() and for each model element the ModelElementId is fetched via IdEObjectCollection.getModelElementId(EObject). Then a mapping between the model element and its ModelElementId is created within the cache.

Specified by:

initMapping in interface IdEObjectCollection

Overrides:

initMapping in class IdEObjectCollectionImpl

See Also:

IdEObjectCollection.initMapping()

initMapping

public void initMapping(Map<org.eclipse.emf.ecore.EObject,String> eObjectToIdMap,
                        Map<String,org.eclipse.emf.ecore.EObject> idToEObjectMap)

/** Initializes the ID caches of the project with the given mappings.

Specified by:

initMapping in interface IdEObjectCollection

Overrides:

initMapping in class IdEObjectCollectionImpl

Parameters:

eObjectToIdMap - a mapping from EObjects to IDs

idToEObjectMap - the reverse mapping of eObjectToIdMap

See Also:

IdEObjectCollectionImpl.initMapping(java.util.Map, java.util.Map)

notify

public void notify(org.eclipse.emf.common.notify.Notification notification,
                   IdEObjectCollection project,
                   org.eclipse.emf.ecore.EObject modelElement)

A notification on a model element of the collection occurred. See Notification documentation for details on the notifications. This method will be called even if the given notification results from an add or remove of a model element of the project.

Specified by:

notify in interface IdEObjectCollectionChangeObserver

Parameters:

notification - the notification

project - the collection holding the modelElement

modelElement - the model element the notification originates from

See Also:

IdEObjectCollectionChangeObserver.notify(org.eclipse.emf.common.notify.Notification, org.eclipse.emf.emfstore.internal.common.model.IdEObjectCollection, org.eclipse.emf.ecore.EObject)

addIdEObjectCollectionChangeObserver

public void addIdEObjectCollectionChangeObserver(IdEObjectCollectionChangeObserver eObjectChangeObserver)

Adds an IdEObjectCollectionChangeObserver to the collection.

Specified by:

addIdEObjectCollectionChangeObserver in interface NotifiableIdEObjectCollection

Parameters:

eObjectChangeObserver - a change observer to be added

See Also:

NotifiableIdEObjectCollection.addIdEObjectCollectionChangeObserver(org.eclipse.emf.emfstore.internal.common.model.util.IdEObjectCollectionChangeObserver)

removeIdEObjectCollectionChangeObserver

public void removeIdEObjectCollectionChangeObserver(IdEObjectCollectionChangeObserver projectChangeObserver)

Remove an IdEObjectCollectionChangeObserver from the collection.

Specified by:

removeIdEObjectCollectionChangeObserver in interface NotifiableIdEObjectCollection

Parameters:

projectChangeObserver - a change observer to be removed

See Also:

public void setUndetachable(IdEObjectCollectionChangeObserver observer)

Make a project change observer undetachable.

Parameters:

observer - the observer

public void modelElementRemoved(IdEObjectCollection projectImpl,
                                org.eclipse.emf.ecore.EObject modelElement)

Called when the eObject and its siblings have been removed from the collection. NOTE: Note that you will NOT receive a separate notification for each sibling.

Specified by:

modelElementRemoved in interface IdEObjectCollectionChangeObserver

Parameters:

projectImpl - the IdEObjectCollection to which the eObject was added

modelElement - the EObject that has been added to the collection

See Also:
