方法详细信息
addingService | () | 方法 |
public function addingService(reference:IServiceReference):com.adobe.gravity.utility.async:IToken| 语言版本: | ActionScript 3.0 |
| 产品版本: | Adobe Digital Enterprise Platform Experience Services - Client Component Framework 10 |

}
参数
reference:IServiceReference — The reference for the new service.
|
com.adobe.gravity.utility.async:IToken — A token used to set success and failure handlers to be called when the operation has completed. The success handler must be called with the object to be returned by the tracker as the service object.

| 产品版本: | Adobe Digital Enterprise Platform Experience Services - Client Component Framework 10 |
| 运行时版本: | AIR 1.1, Flash Player 9 |
Called when service properties are modified.
参数
reference:IServiceReference — The reference for the service.
| |
service:Object — The service object.
|
open | () | 方法 |
public function open():com.adobe.gravity.utility.async:IToken| 语言版本: | ActionScript 3.0 |
