org.eclipse.core.resources.IResourceDelta
A resource delta represents changes in the state of a resource tree between two discrete points in time.
This interface is not intended to be implemented by clients.

Resource deltas implement the IAdaptable interface; extensions are managed by the platform's adapter manager.
