public void dispose()
IContentProvider
The viewer should not be updated during this call, as it is in the process of being disposed.

public void inputChanged(Viewer viewer, Object oldInput, Object newInput)
IContentProvider
A typical use for this method is registering the content provider as a listener to changes on the new input (using model-specific means), and deregistering the viewer from the old input. In response to these change notifications, the content provider should update the viewer (see the add, remove, update and refresh methods on the viewers).
The viewer should not be updated during this call, as it might be in the process of being disposed.

public final void resourceChanged(IResourceChangeEvent event)
IResourceChangeListener
The supplied event gives details. This event object (and the resource delta within it) is valid only for the duration of the invocation of this method.
Note: This method is called by the platform; it is not intended to be called directly by clients.
Note that during resource change event notification, further changes to resources may be disallowed.
