public class ObservableListContentProvider extends Object implements IStructuredContentProvider
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.Constructor and Description |

ObservableListContentProvider()
Constructs an ObservableListContentProvider.

ObservableListContentProvider(IViewerUpdater viewerUpdater)
Constructs an ObservableListContentProvider with the given viewer
updater.

getElements(Object inputElement)
Returns the elements to display in the viewer
when its input is set to the given element.
|
IObservableSet |
getKnownElements()
Returns the set of elements known to this content provider.

- the viewer updater to use when elements are added, removed,
moved or replaced in the input observable list.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.
