autoConnect | 屬性 |
autoConnect:Boolean| 語言版本: | ActionScript 3.0 |
| 產品版本: | BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3 |
| 執行階段版本: | 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.
此屬性可以做為資料繫結的來源。一旦修改此屬性，將傳送 propertyChange 事件。

defaultHeaders:Object| 語言版本: | ActionScript 3.0 |
| 產品版本: | BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3 |
| 執行階段版本: | 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.
此屬性可以做為資料繫結的來源。一旦修改此屬性，將傳送 propertyChange 事件。

priority:int| 語言版本: | ActionScript 3.0 |
| 產品版本: | BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3 |
| 執行階段版本: | 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.
此屬性可以做為資料繫結的來源。一旦修改此屬性，將傳送 propertyChange 事件。

reconnectAttempts:int| 語言版本: | ActionScript 3.0 |
| 產品版本: | BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3 |
| 執行階段版本: | 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.
此屬性可以做為資料繫結的來源。一旦修改此屬性，將傳送 propertyChange 事件。

reconnectInterval:int| 語言版本: | ActionScript 3.0 |
| 產品版本: | BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3 |
| 執行階段版本: | 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.
此屬性可以做為資料繫結的來源。一旦修改此屬性，將傳送 propertyChange 事件。

public function connect():void| 語言版本: | ActionScript 3.0 |
| 產品版本: | BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3 |
| 執行階段版本: | 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.
擲回值
InvalidDestinationError — If no destination is set.

範例
如何使用本範例
var producer:Producer = new Producer();
producer.destination = "TestTopic";
producer.addEventListener(PropertyChangeEvent.PROPERTY_CHANGE, handleConnect);
producer.connect();
disconnect | () | 方法 |
override public function disconnect():void| 語言版本: | ActionScript 3.0 |
| 產品版本: | BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3 |
| 執行階段版本: | 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 | () | 方法 |
public function send(message:IMessage):void| 語言版本: | ActionScript 3.0 |
| 產品版本: | BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3 |
| 執行階段版本: | 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.
參數
message:IMessage — The Message to send.
|
擲回值
InvalidDestinationError — If no destination is set.

範例
如何使用本範例
var producer:Producer = new Producer();
producer.destination = "TestTopic";
var msg:AsyncMessage = new AsyncMessage();
msg.body = "test message";
producer.send(msg);
