Constructor Detail

TreeNodeItemProvider

public TreeNodeItemProvider(AdapterFactory adapterFactory)

This constructs an instance from a factory and a notifier.

Method Detail

setTarget

public void setTarget(Notifier target)

Description copied from interface: Adapter

Sets the target from which the adapter will receive notification. This method is only to be called by a notifier when this adapter is added to or removed from its adapter list. In general, an adapter may be shared by more than one notifier.

Specified by:

setTarget in interface Adapter

Overrides:

setTarget in class ItemProviderAdapter

Parameters:

target - the new notifier.

See Also:

Adapter.getTarget()

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 ItemProviderAdapter

getChildrenFeatures

public 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.

Overrides:

getChildrenFeatures in class ItemProviderAdapter

getParent

public java.lang.Object getParent(java.lang.Object object)

This returns the parent of the TreeNode.

Specified by:

getParent in interface IEditingDomainItemProvider

Specified by:

getParent in interface ITreeItemContentProvider

Overrides:

getParent in class ItemProviderAdapter

getImage

public java.lang.Object getImage(java.lang.Object object)

Description copied from class: ItemProviderAdapter

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

Specified by:

getImage in interface IItemLabelProvider

Overrides:

getImage in class ItemProviderAdapter

getText

public java.lang.String getText(java.lang.Object object)

Description copied from class: ItemProviderAdapter

This implements IItemLabelProvider.getText by simply calling toString on the argument. This will often be correct as is.

Specified by:

getText in interface IItemLabelProvider

Overrides:

getText in class ItemProviderAdapter

notifyChanged

public void notifyChanged(Notification notification)

This handles notification by calling 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.

Specified by:

notifyChanged in interface Adapter

Specified by:

notifyChanged in interface INotifyChangedListener

Overrides:

notifyChanged in class AdapterImpl

Parameters:

notification - a description of the change.

collectNewChildDescriptors

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.

Overrides:

collectNewChildDescriptors in class ItemProviderAdapter

dispose

public void dispose()

Description copied from class: ItemProviderAdapter

This will remove this adapter from all its the targets and dispose any remaining children wrappers in the children store.

Specified by:

dispose in interface IDisposable

Overrides:

dispose in class ItemProviderAdapter
