Interface InquisitiveValueObserver<T>

Type Parameters:

T -

All Superinterfaces:

ValueObserver<T>

All Known Implementing Classes:

LiveValue

public interface InquisitiveValueObserver<T>
extends ValueObserver<T>

An InquisitiveValueObserver is a ValueObserver that inquires about the state of other ObservableValue objects. Such an observer needs to make sure not to access these objects in a potentially outdated state (that may be inconsistent with newer knowledge this observer may have). Therefore, InquisisitiveObservers receive a signal when the other observers have had a chance to update their state, i.e. once all observers have been notified.
