ExclusiveObserverclass encapsulates an object pointer and callback function for an exclusive observer.
template <class observerType, class observableType> class ExclusiveObserver :
public ExclusiveObserverBase<observableType, typename observableType::ObservableEventType>
||The type of the class for which a notification function is called when an event occurs.|
||The type of the class that is being observed. This parameter should be the type of the class that inherits directly from the |
template <class eventType> ExclusiveObserver(observerType *observer, void (observerType::*callback)(observableType *, eventType));
ExclusiveObserver(observerType *observer, void (observerType::*callback)(observableType *));

||A pointer to a member function (the notification function) of the object specified by the |
ExclusiveObserverclass encapsulates a member function of an observer object. Observers are installed on exclusive observable objects by calling the
ExclusiveObservable::SetObserverfunction. Once installed, the member function stored in the observer object is called each time an event is posted for the observable object.
The first parameter of the member function belonging to the observer object is a pointer to the object being observed. If the event type of the observable object is not
void, then the event is passed as the second parameter to the member function. Otherwise, the member function should not take a second parameter.
