Interface IViewerValueProperty<S,T>

Type Parameters:
S - type of the source object
T - type of the value of the property
All Superinterfaces:
IProperty, IValueProperty<S,T>
All Known Implementing Classes:
ViewerValueProperty
public interface IViewerValueProperty<S,T> extends IValueProperty<S,T>
IValueProperty for observing a JFace viewer
Since:
1.3
Restriction:
This interface is not intended to be implemented by clients.

  • Method Details

    • observe

      IViewerObservableValue<T> observe(Viewer viewer)
      Returns an IViewerObservableValue observing this value property on the given viewer
      Parameters:
      viewer - the source viewer
      Returns:
      an observable value observing this value property on the given viewer

    • observe

      IObservableValue<T> observe(S viewer)
      This method is redeclared to trigger ambiguous method errors that are hidden by a suspected Eclipse compiler bug 536911. By triggering the bug in this way clients avoid a change of behavior when the bug is fixed. When the bug is fixed this redeclaration should be removed.
      Specified by:
      observe in interface IValueProperty<S,T>
      Parameters:
      viewer - the property source
      Returns:
      an observable value observing this value property on the given property source

    • observeDelayed

      IViewerObservableValue<T> observeDelayed(int delay, Viewer viewer)
      Returns an IViewerObservableValue observing this value property on the given viewer, which delays notification of value changes until at least delay milliseconds have elapsed since that last change event, or until a FocusOut event is received from the viewer's control (whichever happens first).

      This method is equivalent to ViewersObservables.observeDelayedValue(delay, observe(viewer)).

      Parameters:
      delay - the delay in milliseconds.
      viewer - the source viewer
      Returns:
      an observable value observing this value property on the given viewer, and which delays change notifications for delay milliseconds.
