ApplicationServiceProvider (Silverpeas Core 6.3 API)

java.lang.Object
- org.silverpeas.core.ApplicationServiceProvider

```
@Provider
@Singleton
public class ApplicationServiceProvider
extends Object
```
A provider of objets implementing the ApplicationService interface. The provider looks for an implementation of the ApplicationService interface by the identifier of the application instance. In order the discovery of such a service succeeds, it is required that each implementation are annotated by the @Named annotation with as value the name of the component with the first character in lowercase following by the term Service; for example an application Toto should provide an implementation of the ApplicationService interface named (with the Named annotation) totoService.
