Class TreeItemProviderAdapterFactory

java.lang.Object
  org.eclipse.emf.common.notify.impl.AdapterFactoryImpl
      org.eclipse.emf.edit.tree.util.TreeAdapterFactory
          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.

Field Summary

protected IChangeNotifier	changeNotifier This is used to implement IChangeNotifier.
protected Disposable	disposable 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.

Constructor Summary

TreeItemProviderAdapterFactory()
This constructs an instance.

Method Summary

Adapter	adapt(Notifier notifier, java.lang.Object type) This implementation substitutes the factory itself as the key for the adapter.
java.lang.Object	adapt(java.lang.Object object, java.lang.Object type) Returns either the result of calling adapt(Notifier, Object) or the result of calling resolve(Object, Object), depending on whether the target is a notifier.
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.

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.

Specified by:

adapt in interface AdapterFactory

Overrides:

adapt in class AdapterFactoryImpl

Parameters:

notifier - the notifier to adapt.

type - the key indicating the type of adapter required.

Returns:

a previously existing associated adapter, a new associated adapter if possible, or null otherwise.
