Implementors | Notification |
PureMVC does not rely upon underlying event models such as the one provided with Flash, and ActionScript 3 does not have an inherent event model.
The Observer Pattern as implemented within PureMVC exists to support event-driven communication between the application and the actors of the MVC triad.
Notifications are not meant to be a replacement for Events in Flex/Flash/AIR. Generally, IMediator
implementors place event listeners on their view components, which they then handle in the usual way. This may lead to the broadcast of Notification
s to trigger ICommand
s or to communicate with other IMediators
. IProxy
and ICommand
instances communicate with each other and IMediator
s by broadcasting INotification
s.
A key difference between Flash Event
s and PureMVC Notification
s is that Event
s follow the 'Chain of Responsibility' pattern, 'bubbling' up the display hierarchy until some parent component handles the Event
, while PureMVC Notification
s follow a 'Publish/Subscribe' pattern. PureMVC classes need not be related to each other in a parent/child relationship in order to communicate with one another using Notification
s.
