This class provides a place to set additional or token-level data for
asynchronous RPC operations. It also allows an IResponder to be attached
for an individual call.
The AsyncToken can be referenced in ResultEvent and
FaultEvent from the token property.
Implementation public function get message():IMessage
responders
property
responders:Array [read-only]
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
An array of IResponder handlers that will be called when
the asynchronous request completes.
Eaxh responder assigned to the token will have its result
or fault function called passing in the
matching event before the operation or service dispatches the
event itself.
A developer can prevent the service from subsequently dispatching the
event by calling event.preventDefault().
Note that this will not prevent the service or operation's
result property from being assigned.
Implementation public function get responders():Array
result
property
result:Object [read-only]
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
The result that was returned by the associated RPC call.
Once the result property on the token has been assigned
it will be strictly equal to the result property on the associated
ResultEvent.
This property can be used as the source for data binding.

AsyncToken
()
Constructor
public function AsyncToken(message:IMessage = null)
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
Constructs an instance of the token with the specified message.
Parameters
message:IMessage (default = null) — The message with which the token is associated.
Method Detail
addResponder
()
method
public function addResponder(responder:IResponder):void
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
Adds a responder to an Array of responders.
The object assigned to the responder parameter must implement
mx.rpc.IResponder.
Parameters
responder:IResponder — A handler which will be called when the asynchronous request completes.
Dispatched when a property of the channel set changes.
The PropertyChangeEvent.PROPERTY_CHANGE constant defines the value of the
type property of the event object for a PropertyChange event.
The properties of the event object have the following values:
Property
Value
bubbles
Determined by the constructor; defaults to false.
cancelable
Determined by the constructor; defaults to false.
kind
The kind of change; PropertyChangeEventKind.UPDATE
or PropertyChangeEventKind.DELETE.
oldValue
The original property value.
newValue
The new property value, if any.
property
The property that changed.
source
The object that contains the property that changed.
currentTarget
The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget.
target
The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event.
