Reference to the object that posts the notification (the sender). May be used to filter notifications in the callbacks.
Name of the notification.
mixed $info = array()
Additional information about the notification.
bool $pending = TRUE
Notifications are by default added to a pending notification list. This way, if an observer is not registered by the time they are posted, it will still be notified when it is added as an observer.
This behaviour can be turned off in order to make sure that only the registered observers will be notified.
bool $bubble = TRUE
Notifications are by default added broadcasted to any nested dispatchers that have been added using addNestedDispatcher().
This behaviour can be turned off in order to make sure that only the observers added the posting dispatcher will be notified. This allows you to differentiate between global and local notifications.
