| FAST_UNSAFE_NOTIFY : int = 2 [static] A notification ordering policy wherein the observers are notified
last to first so that they can be removed during the notification
process and new observers added will not inadvertently be notified
as well, but no copy of the observer list need be made.
| ObserverList | ||
| SAFE_IN_ORDER_NOTIFY : int = 1 [static] A notification ordering policy indicating that the observers
should be notified in the order they were added and that the
notification should be done on a snapshot of the array.

| apply | () | method |
public function apply(func:Function):voidApply some operation to all observers. The function to be passed in should expect one argument and either return void or a Boolean. If returning a Boolean, returning false indicates that the observer should be removed from the list.

| FAST_UNSAFE_NOTIFY | constant |
public static const FAST_UNSAFE_NOTIFY:int = 2A notification ordering policy wherein the observers are notified last to first so that they can be removed during the notification process and new observers added will not inadvertently be notified as well, but no copy of the observer list need be made. This will not work if observers are added or removed from arbitrary positions in the list during a notification call.
| SAFE_IN_ORDER_NOTIFY | constant |
public static const SAFE_IN_ORDER_NOTIFY:int = 1A notification ordering policy indicating that the observers should be notified in the order they were added and that the notification should be done on a snapshot of the array.
