Constructor Detail

EReferenceItemProvider

public EReferenceItemProvider(AdapterFactory adapterFactory)
This constructs an instance from a factory and a notifier.

Method Detail

getPropertyDescriptors

public java.util.List<IItemPropertyDescriptor> getPropertyDescriptors(java.lang.Object object)
This returns the property descriptors for the adapted class.

Specified by:
getPropertyDescriptors in interface IItemPropertySource
Overrides:
getPropertyDescriptors in class EStructuralFeatureItemProvider

addContainmentPropertyDescriptor

protected void addContainmentPropertyDescriptor(java.lang.Object object)
This adds a property descriptor for the Containment feature.


addContainerPropertyDescriptor

protected void addContainerPropertyDescriptor(java.lang.Object object)
This adds a property descriptor for the Container feature.


addResolveProxiesPropertyDescriptor

protected void addResolveProxiesPropertyDescriptor(java.lang.Object object)
This adds a property descriptor for the Resolve Proxies feature.


addEOppositePropertyDescriptor

protected void addEOppositePropertyDescriptor(java.lang.Object object)
This adds a property descriptor for the EOpposite feature.


addEReferenceTypePropertyDescriptor

protected void addEReferenceTypePropertyDescriptor(java.lang.Object object)
This adds a property descriptor for the EReference Type feature.


addEKeysPropertyDescriptor

protected void addEKeysPropertyDescriptor(java.lang.Object object)
This adds a property descriptor for the Keys feature.


getImage

createInitializeCopyCommand

protected Command createInitializeCopyCommand(EditingDomain domain,
                                              EObject owner,
                                              CopyCommand.Helper helper)
This creates a custom initialize copy command that specially handles the eOpposite like it is bidirectional, itself.

Overrides:
createInitializeCopyCommand in class ItemProviderAdapter

notifyChanged

public void notifyChanged(Notification notification)
This handles model notifications by calling ItemProviderAdapter.updateChildren(org.eclipse.emf.common.notify.Notification) to update any cached children and by creating a viewer notification, which it passes to ItemProviderAdapter.fireNotifyChanged(org.eclipse.emf.common.notify.Notification).

Specified by:
notifyChanged in interface Adapter
