Data Binding

  • Delayed observables? Only update after a few seconds...not on every keypress
    • org.eclipse.core.internal.databinding.observable.DelayedObservableValue
    • from Observables.observeDelayedValue() 
      /**
 * {@link IObservableValue} implementation that wraps an
 * {@link IObservableValue} and delays notification of value change events from
 * the wrapped observable value until a certain time has passed since the last
 * change event. This class helps to boost performance in bindings (both in
 * validation and in event firing) when the observed value is rapidly changing.
 * A common use of this class is to delay validation until the user stops typing
 * in an UI field. To notify about pending changes, a DelayedObservableValue
 * fires a stale event when the wrapped observable value fires a change event,
 * and remains stale as long as a value change is pending.
 * 
 * Note that this class will not forward {@link ValueChangingEvent} events from
 * a wrapped {@link IVetoableValue}.
 * 
 * @since 1.2
