ExpressionsItemProviderAdapterFactory (CDO Model Repository Documentation)

java.lang.Object
- org.eclipse.emf.common.notify.impl.AdapterFactoryImpl
- - org.eclipse.emf.cdo.expressions.util.ExpressionsAdapterFactory
  - - org.eclipse.emf.cdo.expressions.provider.ExpressionsItemProviderAdapterFactory

All Implemented Interfaces:

org.eclipse.emf.common.notify.AdapterFactory, org.eclipse.emf.edit.provider.ComposeableAdapterFactory, org.eclipse.emf.edit.provider.IChangeNotifier, org.eclipse.emf.edit.provider.IChildCreationExtender, org.eclipse.emf.edit.provider.IDisposable
```
public class ExpressionsItemProviderAdapterFactory
extends ExpressionsAdapterFactory
implements org.eclipse.emf.edit.provider.ComposeableAdapterFactory, org.eclipse.emf.edit.provider.IChangeNotifier, org.eclipse.emf.edit.provider.IDisposable, org.eclipse.emf.edit.provider.IChildCreationExtender
```
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.
