Geeft aan of voor een object een opgegeven eigenschap is gedefinieerd. | Object | ||
Returns true if there are any pending requests for the passed in message. | MessageAgent | ||
Called after the implementing object has been created
and all properties specified on the tag have been assigned. | MessageAgent | ||
Geeft aan of een instantie van de klasse Object zich in de prototypeketen van het object bevindt dat als parameter is opgegeven. | Object | ||
Logs the MessageAgent out from its remote destination. | MessageAgent | ||
Geeft aan of de opgegeven eigenschap bestaat en kan worden opgesomd. | Object | ||
Requests any messages that are queued for this Consumer on the server. | AbstractConsumer | ||
Verwijdert een listener uit het object EventDispatcher. | EventDispatcher | ||
Sets the credentials that the MessageAgent uses to authenticate to
destinations. | MessageAgent | ||
Stelt de beschikbaarheid van een dynamische eigenschap voor lusbewerkingen in. | Object | ||
Sets the remote credentials that will be passed through to the remote destination
for authenticating to secondary systems. | MessageAgent | ||
Subscribes to the remote destination. | AbstractConsumer | ||
Geeft de tekenreeksweergave van dit object weer, geformatteerd volgens de locatiespecifieke conventies. | Object | ||
Retourneert een tekenreeksrepresentatie van het opgegeven object. | Object | ||
Unsubscribes from the remote destination. | AbstractConsumer | ||
Retourneert de primitieve waarde van het opgegeven object. | Object | ||

selector:String
Taalversie: | ActionScript 3.0 |
Productversies: | BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3 |
Runtimeversies: | Flash Player 9, AIR 1.1 |
The selector for the Consumer. This is an expression that is passed to the destination which uses it to filter the messages delivered to the Consumer.
Before a call to the subscribe()
method, this property
can be set with no side effects.
After the Consumer has subscribed to its destination, changing this
value has the side effect of updating the Consumer's subscription to
use the new selector expression immediately.
The remote destination must understand the value of the selector expression.
Deze eigenschap kan als de bron voor gegevensbinding worden gebruikt. Wanneer deze eigenschap wordt gewijzigd, wordt de gebeurtenis propertyChange
verzonden.

Constructor.
ParametersmessageType:String (default = "flex.messaging.messages.AsyncMessage ") — The alias for the message type processed by the service
hosting the remote destination the Consumer will subscribe to.
This parameter is deprecated and it is ignored by the
constructor.

Voorbeeld ( Hoe dit voorbeeld te gebruiken )
function initConsumer():void { var consumer:Consumer = new Consumer(); consumer.destination = "NASDAQ"; consumer.selector = "operation IN ('Bid','Ask')"; consumer.addEventListener(MessageEvent.MESSAGE, messageHandler); consumer.subscribe(); } function messageHandler(event:MessageEvent):void { var msg:IMessage = event.message; var info:Object = msg.body; trace("-App recieved message: " + msg.toString()); }

mx.messaging.events.MessageEvent
eigenschap MessageEvent.type =
mx.messaging.events.MessageEvent.MESSAGE
Taalversie: | ActionScript 3.0 |
Productversies: | BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3 |
Runtimeversies: | Flash Player 9, AIR 1.1 |
Dispatched when a message is received by the Consumer.
The MESSAGE event type; dispatched upon receipt of a message.The value of this constant is "message"
.
The properties of the event object have the following values:
Property | Value |
---|---|
bubbles | false |
cancelable | false |
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 . |
message | The message associated with this event. |
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. |
