Constructor Summary | |
TreeNodeItemProvider(AdapterFactory adapterFactory)
This constructs an instance from a factory and a notifier. |
Method Summary | |
protected void |
collectNewChildDescriptors(Collection newChildDescriptors,
Object object)
This adds to the collection of CommandParameter s
describing all of the children that can be created under this object. |
void |
dispose()
This will remove this adapter from all its the targets and dispose any remainging children wrappers in the children store. |
Collection |
getChildrenFeatures(Object object)
This specifies how to implement ItemProviderAdapter.getChildren(java.lang.Object) and is used to deduce an appropriate feature for an
AddCommand , RemoveCommand or
MoveCommand in ItemProviderAdapter.createCommand(java.lang.Object, org.eclipse.emf.edit.domain.EditingDomain, java.lang.Class, org.eclipse.emf.edit.command.CommandParameter) |
Object |
getImage(Object object)
This does the same thing as ILabelProvider.getImage, it fetches the label image specific to this object instance. |
Object |
getParent(Object object)
This returns the parent of the TreeNode. |
List |
getPropertyDescriptors(Object object)
This returns the property descriptors for the adapted class. |
String |
getText(Object object)
This does the same thing as ILabelProvider.getlText, it fetches the label text specific to this object instance. |
void |
notifyChanged(Notification notification)
This handles notification by calling fireNotifyChanged .
|
void |
setTarget(Notifier target)
Sets the target from which the adapter will receive notification. |

fireNotifyChanged
.
This will also be called by the delegateItemProvider
when it normally fires a notification to its adapter factory;
the listener method is hooked up in setTarget
. Notifications are wrapped to look like they originate from
the target.
