Overview
Classes: AbstractObserver, AsyncNotificationCenter, AsyncObserver, NObserver, Notification, NotificationCenter, NotificationQueue, Observer, PriorityNotificationQueue, TimedNotificationQueue
Classes
class AbstractObserver
The base class for all instantiations of
the Observer and NObserver template classes. 
class AsyncNotificationCenter
AsyncNotificationCenter decouples posting of notifications
from notifying subscribers by calling observers' notification
handler in a dedicated thread.
class AsyncObserver
AsyncObserver notifies subscribers in a dedicated thread (as opposed
to (N)Observer classes, which notify subscribers synchronously).
class NObserver
This template class implements an adapter that sits between
a NotificationCenter and an object receiving notifications
from it.
class Notification
The base class for all notification classes used
with the NotificationCenter and the NotificationQueue
classes.
class NotificationCenter
A NotificationCenter is essentially a notification dispatcher.
class NotificationQueue
A NotificationQueue object provides a way to implement asynchronous
notifications.
class Observer
This template class implements an adapter that sits between
a NotificationCenter and an object receiving notifications
from it.
class PriorityNotificationQueue
A PriorityNotificationQueue object provides a way to implement asynchronous
notifications.
class TimedNotificationQueue
A TimedNotificationQueue object provides a way to implement timed, asynchronous
notifications.
