-now, we explain what the new interfaces look like: Indeed as you can imagine,
there is an issue when
-you extend the Component interface, because the various Component setter
methods return a Component type.
-So, what we would like is to be able to introduce a generic type in the
Component interface , and such
-generic type can then be used to allow the Component setter methods to return
not the Component type,
-but instead return the aspect/adapter sub classes. This is what we have done,
let's show a pseudo code,
-so you can understand how it works:
-
-First, the Component annotation have been reworked like this:
-
- :::java
- public interface Component<T extends Component<T>> {
- T setInterface(String service, Dictionary properties)
- T setImplementation(Object ob);
- ...
- }
-
-As you can see the Component annotation is now using a recursive generic type
which extends the Component interface.
-And now we have for example the following AdapterComponent interface which is
defined like this:
-
- :::java
- public interface AdapterComponent extends Component<AdapterComponent> {
- AdapterComponent setAdaptee(Class<?> service, String filter);
- AdapterComponent setAdapteeCallbacks(String add, String change, String
remove, String swap);
- ...
- }
-
-So, now, an adapter component can be defined like this:
-
- :::java
- Component adapter = createAdapterComponent()
- .setAdaptee(Adaptee.class, "(foo=bar)")
- .setAdapteeCallbacks("setAdaptee", "changeAdaptee", null, null)
- .setImplementation(AdapterImpl.class)
- .setInterface(AdapterService.class, null)
- .add(createServiceDependency().setService(LogService.class));
