Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`IViewerObservableValue`	`observe(Viewer viewer)`	Returns an `IViewerObservableValue` observing this value property on the given viewer
`IViewerObservableValue`	`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).

- Method Detail
  - observe
```
IViewerObservableValue 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
  - observeDelayed
```
IViewerObservableValue 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.
