org.eclipse.emf.edit.provider
Class ReflectiveItemProvider

java.lang.Object
  org.eclipse.emf.common.notify.impl.AdapterImpl
      org.eclipse.emf.edit.provider.ItemProviderAdapter
          org.eclipse.emf.edit.provider.ReflectiveItemProvider

All Implemented Interfaces:

Adapter, CreateChildCommand.Helper, IChangeNotifier, IDisposable, IEditingDomainItemProvider, IItemLabelProvider, IItemPropertySource, IStructuredItemContentProvider, ITreeItemContentProvider, ResourceLocator

public class ReflectiveItemProvider

extends ItemProviderAdapter

implements IEditingDomainItemProvider, IStructuredItemContentProvider, ITreeItemContentProvider, IItemLabelProvider, IItemPropertySource

This adapter implementation provides reflective support that emulates the behaviour of a default generated item provider.

Method Summary

protected void	collectNewChildDescriptors(Collection newChildDescriptors, Object object) This adds to newChildDescriptors, a collection of CommandParameters, parameters for possible children of the specified object, when viewed as an instance of the type for which this is an item provider.
protected List	getAllConcreteSubclasses(EClass eClass)
protected List	getAllEClasses(EClass eClass)
protected Collection	getChildrenFeatures(Object object) If this is defined to be something other than an empty list, it is used to implement getChildren, including in determining whether to cache children and, if so, in setting up the store.
Object	getCreateChildImage(Object owner, Object feature, Object child, Collection selection) This returns the icon image for CreateChildCommand.
protected String	getFeatureText(Object feature) This looks up the name of the specified feature.
Object	getImage(Object object) This does the same thing as ILabelProvider.getImage, it fetches the label image specific to this object instance.
protected EStructuralFeature	getLabelFeature(EClass eClass)
List	getPropertyDescriptors(Object object) This does the same thing as IPropertySource.getPropertyDescriptors.
String	getText(Object object) This does the same thing as ILabelProvider.getlText, it fetches the label text specific to this object instance.
protected String	getTypeText(Object object) This looks up the name of the type of the specified object.
void	notifyChanged(Notification notification) Does nothing; clients may override so that it does something.

public ReflectiveItemProvider(AdapterFactory adapterFactory)

Method Detail

getPropertyDescriptors

public List getPropertyDescriptors(Object object)

Description copied from interface: IItemPropertySource

This does the same thing as IPropertySource.getPropertyDescriptors.

Specified by:

getPropertyDescriptors in interface IItemPropertySource

Overrides:

getPropertyDescriptors in class ItemProviderAdapter

getAllEClasses

protected List getAllEClasses(EClass eClass)

getAllConcreteSubclasses

protected List getAllConcreteSubclasses(EClass eClass)

getChildrenFeatures

protected Collection getChildrenFeatures(Object object)

Description copied from class: ItemProviderAdapter

If this is defined to be something other than an empty list, it is used to implement getChildren, including in determining whether to cache children and, if so, in setting up the store. It is also used to deduce the appropriate feature for an AddCommand, RemoveCommand or MoveCommand in createCommand. If you override those methods, then you don't need to implement this.

Overrides:

getChildrenFeatures in class ItemProviderAdapter

getImage

public Object getImage(Object object)

Description copied from interface: IItemLabelProvider

This does the same thing as ILabelProvider.getImage, it fetches the label image specific to this object instance.

Specified by:

getImage in interface IItemLabelProvider

Overrides:

getImage in class ItemProviderAdapter

getText

public String getText(Object object)

Description copied from interface: IItemLabelProvider

This does the same thing as ILabelProvider.getlText, it fetches the label text specific to this object instance.

Specified by:

getText in interface IItemLabelProvider

Overrides:

getText in class ItemProviderAdapter

getLabelFeature

protected EStructuralFeature getLabelFeature(EClass eClass)

collectNewChildDescriptors

protected void collectNewChildDescriptors(Collection newChildDescriptors,
                                          Object object)

Description copied from class: ItemProviderAdapter

This adds to newChildDescriptors, a collection of CommandParameters, parameters for possible children of the specified object, when viewed as an instance of the type for which this is an item provider. This implementation adds nothing to the collection, but derived classes should override this method, invoking the superclass implementation and then adding to the collection.

Overrides:

collectNewChildDescriptors in class ItemProviderAdapter

getCreateChildImage

public Object getCreateChildImage(Object owner,
                                  Object feature,
                                  Object child,
                                  Collection selection)

Description copied from class: ItemProviderAdapter

This returns the icon image for CreateChildCommand.

Specified by:

getCreateChildImage in interface CreateChildCommand.Helper

Overrides:

getCreateChildImage in class ItemProviderAdapter

getTypeText

protected String getTypeText(Object object)

Description copied from class: ItemProviderAdapter

This looks up the name of the type of the specified object.

Overrides:

getTypeText in class ItemProviderAdapter

getFeatureText

protected String getFeatureText(Object feature)

Description copied from class: ItemProviderAdapter

This looks up the name of the specified feature.

Overrides:

getFeatureText in class ItemProviderAdapter

notifyChanged

public void notifyChanged(Notification notification)

Description copied from class: AdapterImpl

Does nothing; clients may override so that it does something.

Specified by:

notifyChanged in interface Adapter

Overrides:

notifyChanged in class AdapterImpl
