Descrizione delle proprietà

autoConnect

proprietà

autoConnect:Boolean

Versione linguaggio:

ActionScript 3.0

Versioni prodotto:

BlazeDS 4, Adobe Digital Enterprise Platform Data Services per Java EE 3

Versioni runtime:

Flash Player 9, AIR 1.1

If true the Producer automatically connects to its destination the first time the send() method is called. If false then the connect() method must be called explicitly to establish a connection to the destination. By default this property is true, but applications that need to operate in an offline mode may set this to false to prevent the send() method from connecting implicitly.

Questa proprietà può essere utilizzata come origine per l’associazione di dati. Quando questa proprietà viene modificata, invia l’evento propertyChange .

Implementazione
public function get autoConnect():Boolean
public function set autoConnect(value:Boolean):void

defaultHeaders

proprietà

defaultHeaders:Object

Versione linguaggio:

ActionScript 3.0

Versioni prodotto:

BlazeDS 4, Adobe Digital Enterprise Platform Data Services per Java EE 3

Versioni runtime:

Flash Player 9, AIR 1.1

The default headers to apply to messages sent by the Producer. Any default headers that do not exist in the message will be created. If the message already contains a matching header, the value in the message takes precedence and the default header value is ignored.

Questa proprietà può essere utilizzata come origine per l’associazione di dati. Quando questa proprietà viene modificata, invia l’evento propertyChange .

Implementazione
public function get defaultHeaders():Object
public function set defaultHeaders(value:Object):void

priority

proprietà

priority:int

Versione linguaggio:

ActionScript 3.0

Versioni prodotto:

BlazeDS 4, Adobe Digital Enterprise Platform Data Services per Java EE 3

Versioni runtime:

Flash Player 9, AIR 1.1

The default message priority for the messages sent by the Producer. The valid values are 0 to 9 (0 being lowest) and -1 means that the Producer does not have a priority set. Note that if the message already has a priority defined, that takes precedence over Producer's priority.

Questa proprietà può essere utilizzata come origine per l’associazione di dati. Quando questa proprietà viene modificata, invia l’evento propertyChange .

Implementazione
public function get priority():int
public function set priority(value:int):void

reconnectAttempts

proprietà

reconnectAttempts:int

Versione linguaggio:

ActionScript 3.0

Versioni prodotto:

BlazeDS 4, Adobe Digital Enterprise Platform Data Services per Java EE 3

Versioni runtime:

Flash Player 9, AIR 1.1

The number of reconnect attempts that the Producer makes in the event that the destination is unavailable or the connection to the destination closes. A value of -1 enables infinite attempts. A value of zero disables reconnect attempts.

Reconnect attempts are made at a constant rate according to the reconnect interval value. When a reconnect attempt is made if the underlying channel for the Producer is not connected or attempting to connect the channel will start a connect attempt. Subsequent Producer reconnect attempts that occur while the underlying channel connect attempt is outstanding are effectively ignored until the outstanding channel connect attempt succeeds or fails.

Questa proprietà può essere utilizzata come origine per l’associazione di dati. Quando questa proprietà viene modificata, invia l’evento propertyChange .

Implementazione
public function get reconnectAttempts():int
public function set reconnectAttempts(value:int):void

reconnectInterval

proprietà

reconnectInterval:int

Versione linguaggio:

ActionScript 3.0

Versioni prodotto:

BlazeDS 4, Adobe Digital Enterprise Platform Data Services per Java EE 3

Versioni runtime:

Flash Player 9, AIR 1.1

The number of milliseconds between reconnect attempts. If a Producer doesn't receive an acknowledgement for a connect attempt, it will wait the specified number of milliseconds before making a subsequent reconnect attempt. Setting the value to zero disables reconnect attempts.

Reconnect attempts are made at a constant rate according to this value. When a reconnect attempt is made if the underlying channel for the Producer is not connected or attempting to connect the channel will start a connect attempt. Subsequent Producer reconnect attempts that occur while the underlying channel connect attempt is outstanding are effectively ignored until the outstanding channel connect attempt succeeds or fails.

Questa proprietà può essere utilizzata come origine per l’associazione di dati. Quando questa proprietà viene modificata, invia l’evento propertyChange .

ArgumentError — If the assigned value is negative.

Descrizione dei metodi

connect

()

metodo

public function connect():void

Versione linguaggio:

ActionScript 3.0

Versioni prodotto:

BlazeDS 4, Adobe Digital Enterprise Platform Data Services per Java EE 3

Versioni runtime:

Flash Player 9, AIR 1.1

Connects the Producer to its target destination. When a connection is established the connected property will change to true and this property is bindable and generates PropertyChangeEvents. The internal TRIGGER_CONNECT_OPERATION CommandMessage that is sent will result in an acknowledge or fault event depending upon whether the underlying channel establishes its connection.

Genera

InvalidDestinationError — If no destination is set.

Esempio
Come utilizzare questo esempio

         var producer:Producer = new Producer();
         producer.destination = "TestTopic";
         producer.addEventListener(PropertyChangeEvent.PROPERTY_CHANGE, handleConnect);
         producer.connect();

disconnect

()

metodo

override public function disconnect():void

Versione linguaggio:

ActionScript 3.0

Versioni prodotto:

BlazeDS 4, Adobe Digital Enterprise Platform Data Services per Java EE 3

Versioni runtime:

Flash Player 9, AIR 1.1

Disconnects the Producer from its remote destination. This method does not wait for outstanding network operations to complete. After invoking disconnect(), the Producer will report that it is not connected and it will not receive any outstanding message acknowledgements or faults. Disconnecting stops automatic reconnect attempts if they are running.

send

()

metodo

public function send(message:IMessage):void

Versione linguaggio:

ActionScript 3.0

Versioni prodotto:

BlazeDS 4, Adobe Digital Enterprise Platform Data Services per Java EE 3

Versioni runtime:

Flash Player 9, AIR 1.1

Sends the specified message to its destination. If the producer is being used for publish/subscribe messaging, only messages of type AsyncMessage should be sent unless a custom message type is being used and the message destination on the server has been configured to process the custom message type.

Parametri

message:IMessage — The Message to send.

Genera

InvalidDestinationError — If no destination is set.

Esempio
Come utilizzare questo esempio

         var producer:Producer = new Producer();
         producer.destination = "TestTopic";
         var msg:AsyncMessage = new AsyncMessage();
         msg.body = "test message";
         producer.send(msg);
