Class TreeItemProviderAdapterFactory

java.lang.Object
  extended by org.eclipse.emf.common.notify.impl.AdapterFactoryImpl
      extended by org.eclipse.emf.edit.tree.util.TreeAdapterFactory
          extended by org.eclipse.emf.edit.tree.provider.TreeItemProviderAdapterFactory
All Implemented Interfaces:
AdapterFactory, ComposeableAdapterFactory, IChangeNotifier, IDisposable

public class TreeItemProviderAdapterFactory
extends TreeAdapterFactory
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 property sheets. Note that most of the adapters are shared among multiple instances.

          This is used to implement IDisposable.
protected  ComposedAdapterFactory parentAdapterFactory
          This keeps track of the root adapter factory that delegates to this adapter factory.
protected  java.util.Collection<java.lang.Object> supportedTypes
          This keeps track of all the supported types checked by isFactoryForType.

Method Summary
 Adapter adapt(Notifier notifier, java.lang.Object type)

 Adapter adaptNew(Notifier object, java.lang.Object type)
          This records adapters for subsequent disposable.
 void addListener(INotifyChangedListener notifyChangedListener)
          This adds a listener.
 Adapter createTreeNodeAdapter()
          This creates an adapter for a TreeNode.
 void dispose()
          This disposes all the disposables.
 void fireNotifyChanged(Notification notification)
          This delegates to changeNotifier and to parentAdapterFactory.
 ComposeableAdapterFactory getRootAdapterFactory()
          This returns the root adapter factory that contains this factory.
 boolean isFactoryForType(java.lang.Object type)
          This also check if the type is one of the supported types.
 void removeListener(INotifyChangedListener notifyChangedListener)
          This removes a listener.
 void setParentAdapterFactory(ComposedAdapterFactory parentAdapterFactory)
          This sets the composed adapter factory that contains this factory.

isFactoryForType

public boolean isFactoryForType(java.lang.Object type)
This also check if the type is one of the supported types.

Specified by:
isFactoryForType in interface AdapterFactory
Overrides:
isFactoryForType in class TreeAdapterFactory
Parameters:
type - the key indicating the type of adapter in question.
Returns:
whether this factory is applicable for the type of the object.
