public class AspectJInjection
extends org.eiichiro.jazzmaster.frontend.Injection

AspectJInjection is Injection extension implementation to inject Jazzmaster service into application frontend with AspectJ 5. With Jazzmaster built-in Injection, you need to implement the following code to get a service injected application frontend:

 HelloFrontend frontend = Application.getFrontend(HelloFrontend.class);
 

With AspectJInjection, you can get it with the following code:

 HelloFrontend helloFrontend = new HelloFrontend();
 

AspectJInjection is implemented as the aspect and weaven into initialization (constructor execution) of @Frontend annotated class. So, though you instantiate application frontend directly, you can get the frontend instance that service has been injected. AspectJInjection does not only make your code simple, but also make easy to integrate Jazzmaster application frontend with third-party libraries. For example, in case of using Apache Struts Action as Jazzmaster application frontend. If you use Jazzmaster built-in Injection, you need to customize the code of Apache Struts instantiating an Action class. If you use AspectJInjection, the code of service injection has been weaven into Action constructor. Therefore, you can use Apache Struts Action as Jazzmaster application frontend with NO Struts code enhancement.
