Method Detail
addingService | () | method |
public function addingService(reference:IServiceReference):com.adobe.gravity.utility.async:IToken| Language Version: | ActionScript 3.0 |
| Product Version: | Adobe Digital Enterprise Platform Experience Services - Client Component Framework 10 |

return BundleContext.currentContext.getService(reference);
}
Parameters
reference:IServiceReference — The reference for the new service.
