`DependencyAnnotation` is used by the framework to extend DI.
|
|
|
|
Only annotations implementing `DependencyAnnotation` are added to the list of dependency properties.
|
|
|
|
For example:
|
|
|
|
```
|
|
class Parent extends DependencyAnnotation {}
|
|
class NotDependencyProperty {}
|
|
|
|
class AComponent {
|
|
constructor(@Parent @NotDependencyProperty aService:AService) {}
|
|
}
|
|
```
|
|
|
|
will create the following dependency:
|
|
|
|
```
|
|
new Dependency(Key.get(AService), [new Parent()])
|
|
```
|
|
|
|
The framework can use `new Parent()` to handle the `aService` dependency
|
|
in a specific way.
