Interface ItemTreeContentProvider

All Superinterfaces:

ItemStructuredContentProvider

All Known Implementing Classes:

ItemTreeContentProvider.Null

public interface ItemTreeContentProvider
extends ItemStructuredContentProvider

Implementations of this interface can be used to maintain the content of a specific tree element. The implementation will monitor the element for any changes that affect the element's 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.
