|---|---|---|---|
 | constructor : Object
類別物件的參照或是特定物件實體的建構函數。 | Object | |
| lastResult : Object [唯讀]
The result of the last invocation. | AbstractInvoker | ||
| makeObjectsBindable : Boolean
When this value is true, anonymous objects returned are forced to bindable objects. | AbstractInvoker | ||
| operationManager : Function
This property is set usually by framework code which wants to modify the
behavior of a service invocation without modifying the way in which the
service is called externally. | AbstractInvoker | ||
| resultElementType : Class
Like resultType, used to define the ActionScript class used by a given operation though
this property only applies to operations which return a multi-valued result (e.g. | AbstractInvoker | ||

Specifies an optional return type for the operation. | AbstractInvoker | ||

operationManager | 屬性 |
public var operationManager:Function| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
This property is set usually by framework code which wants to modify the behavior of a service invocation without modifying the way in which the service is called externally. This allows you to add a "filter" step on the method call to ensure for example that you do not return duplicate instances for the same id or to insert parameters for performing on-demand paging. When this is set to a non-null value on the send call, the operationManager function is called instead. It returns the token that the caller uses to be notified of the result. Typically the called function will at some point clear this property temporarily, then invoke the operation again actually sending it to the server this time.
resultElementType | 屬性 |
public var resultElementType:Class| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Like resultType, used to define the ActionScript class used by a given operation though this property only applies to operations which return a multi-valued result (e.g. an Array or ArrayCollection (IList)). This property specifies an ActionScript class for the members of the array or array collection. When you set resultElementType, you do not have to set resultType. In that case, the operation returns an Array if makeObjectsbindable is false and an ArrayCollection otherwise.
resultType | 屬性 |
public var resultType:Class| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Specifies an optional return type for the operation. Used in situations where you want to coerce the over-the-wire information into a specific ActionScript class or to provide metadata for other services as to the return type of this operation.
cancel | () | 方法 |
public function cancel(id:String = null):mx.rpc:AsyncToken| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Cancels the last service invocation or an invokation with the specified ID. Even though the network operation may still continue, no result or fault event is dispatched.
參數
id:String (default = null) |
mx.rpc:AsyncToken — The AsyncToken associated with the call that is cancelled or null if no call was cancelled.
|
clearResult | () | 方法 |
public function clearResult(fireBindingEvent:Boolean = true):void| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Sets the result property of the invoker to null.
This is useful when the result is a large object that is no longer being
used.
參數
fireBindingEvent:Boolean (default = true)true if you want anything
bound to the result to update. Otherwise, set to
false.
The default value is true
|
setResult | () | 方法 |
public function setResult(result:Object):void| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
This hook is exposed to update the lastResult property. Since lastResult is ordinarily updated automatically by the service, you do not typically call this. It is used by managed services that want to ensure lastResult always points to "the" managed instance for a given identity even if the the service returns a new copy of the same object.
參數
result:Object — The new value for the lastResult property.
