Hi,
I'm a newbie on guice and tried to find the inverse annotation of
@ImplementedBy where a class can define that it provides the default
implementation of an interface?
An example:
I have a class that requires a Component for a field:
@Inject
private Component component;
Then I have the Component interface that specifies the implementing
class:
@ImplementedBy(ComponentImpl.class)
public interface Component() { ... }
This approach has a major drawback, the interface has a dependency to
the implementation class. In order to avoid that design problem, you
need the inverse annotation, something like:
@Provides(Component.class)
public class ComponentImpl() { ... }
But that seems to be not possible in guice. The only thing I found is
to provide a factory method with the @Provides annotation.
Am I missing something here? Or is that feature already planned in a
future release?
