java.lang.Objectorg.eclipse.jface.databinding.viewers.ObservableListContentProvider
A content provider for
AbstractTableViewer or AbstractListViewer that provides
elements of an IObservableList when set as the viewer's input.
Objects of this class listen for changes to the observable list, and will
insert and remove viewer elements to reflect observed changes.
This class is not intended to be subclassed by clients.

public void inputChanged(Viewer viewer,
Object oldInput,
Object newInput)
IContentProviderA 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.

IStructuredContentProviderNOTE: For instances where the viewer is displaying a tree containing a single 'root' element it is still necessary that the 'input' does not return itself from this method. This leads to recursion issues (see bug 9262).
