Class KEGItemProviderAdapterFactory

java.lang.Object
  extended by org.eclipse.emf.common.notify.impl.AdapterFactoryImpl
      extended by de.cau.cs.kieler.keg.util.KEGAdapterFactory
          extended by de.cau.cs.kieler.keg.provider.KEGItemProviderAdapterFactory
All Implemented Interfaces:
AdapterFactory, ComposeableAdapterFactory, IChangeNotifier, IDisposable

public class KEGItemProviderAdapterFactory
extends KEGAdapterFactory
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.
