Interface ItemTreeContentProvider

All Superinterfaces:

ItemContentProvider

public interface ItemTreeContentProvider
extends ItemContentProvider

Implementations of this interface can be used to maintain the content of a specific (non-root) tree item. The implementation will monitor the item for any changes that affect the item's list of children and forward them appropriately to the ItemTreeContentProvider.Manager.

Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
