Class ChangeItemProviderAdapterFactory

java.lang.Object

org.eclipse.emf.common.notify.impl.AdapterFactoryImpl

org.eclipse.emf.ecore.change.util.ChangeAdapterFactory

org.eclipse.emf.ecore.change.provider.ChangeItemProviderAdapterFactory

All Implemented Interfaces:

AdapterFactory, ComposeableAdapterFactory, IChangeNotifier, IDisposable

public class ChangeItemProviderAdapterFactory
extends ChangeAdapterFactory
implements ComposeableAdapterFactory, IChangeNotifier, IDisposable

This is the factory that is used to provide the interfaces needed to support Viewers. The adapters generated by this factory convert EMF adapter notifications into calls to fireNotifyChanged. The adapters also support Eclipse property sheets. Note that most of the adapters are shared among multiple instances.
