TreeNodeItemProvider(AdapterFactory adapterFactory)
This constructs an instance from a factory and a notifier. |
|
| Method Summary | |
|---|---|
protected void |
collectNewChildDescriptors(java.util.Collection<java.lang.Object> newChildDescriptors,
java.lang.Object object)
This adds CommandParameters describing 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. |
java.util.Collection<? extends EStructuralFeature> |
getChildrenFeatures(java.lang.Object object)
This specifies how to implement getChildren and is used to deduce an appropriate feature for an
AddCommand, RemoveCommand or
MoveCommand in createCommand |
java.lang.Object |
getImage(java.lang.Object object)
This implements IItemLabelProvider.getImage by returning null. |
java.lang.Object |
getParent(java.lang.Object object)
This returns the parent of the TreeNode. |
java.util.List<IItemPropertyDescriptor> |
getPropertyDescriptors(java.lang.Object object)
This returns the property descriptors for the adapted class. |
java.lang.String |
getText(java.lang.Object object)
This implements IItemLabelProvider.getText by simply calling toString on the argument. |
void |
notifyChanged(Notification notification)
This handles notification by calling fireNotifyChanged. |
void |
setTarget(Notifier target)
Sets the target from which the adapter will receive notification. |

ItemProviderAdapterIItemLabelProvider.getImage by returning null.
Most things really should have an icon, but not having one is technically correct too.

ItemProviderAdapterIItemLabelProvider.getText by simply calling toString on the argument.
This will often be correct as is.
getText in interface IItemLabelProvidergetText in class ItemProviderAdapterpublic void notifyChanged(Notification 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.
