org.eclipse.core.internal.databinding.validation.ValidatedObservableValue

An {@link IObservableValue} wrapper that stays in sync with the targetobservable as long as a given validation status is valid.

While status is valid, ValidatedObservableValue stays in sync with its target.
When status becomes invalid, ValidatedObservableValue will retain the last valid value of its target.
While status is invalid, changes in the target observable cause ValidatedObservableValue to fire a stale event, to indicate that changes are pending.
When status becomes valid, pending value changes are performed (if any) and synchronization resumes.

Note:

By default, a status is valid if its {@link IStatus#getSeverity() severity} is {@link IStatus#OK OK}, {@link IStatus#INFO INFO}, or {@link IStatus#WARNING WARNING}
Calls to {@link #setValue(Object)} on the validated observable changesthe value regardless of the validation status.
This class will not forward {@link ValueChangingEvent} events from awrapped {@link IVetoableValue}.
