public class WorkbenchAdapterContentProvider
extends java.lang.Object
implements org.eclipse.jface.viewers.ITreeContentProvider, org.eclipse.core.resources.IResourceChangeListener

Tree content provider that used the Eclipse's adapter framework. All the methods are delegated to an adapter that is an instance of IWorkbenchAdapter.

One of the functions available in this content provider is to monitor changes in workspace triggering refreshes and updates in a IResourceChangeUpdater. If no updater is available then the changes are not processed.

This implementation is based on the WorkbenchContentProvider class.
