Kuidas rakendatakse sõltuvuste süstimist Daggeris, kasutades annotatsioone sõltuvuste komponentide sees?

In Dagger, dependency injection via annotations within dependent components is implemented using the annotations @Component and @Subcomponent.

  • The main component (@Component) provides dependencies.
  • The dependent component (@Subcomponent) is declared within the main and can inherit dependencies.

Example:

@Subcomponent
public interface ChildComponent {
    void inject(SomeClass target);
}

@Component
public interface ParentComponent {
    ChildComponent childComponent();
}

Here, ChildComponent depends on ParentComponent and can use its dependencies. Annotations allow Dagger to generate code for automatic dependency injection into the necessary classes.
