I'm not sure. But here is my problem precisely. I'm using an abstract class
inside the factory and bindind that implementation.
Example:
public interface ResourceFactory {
Resource domainResource(Domain target);
}
public abstract class Resource{}
public MyResource extends Resource{}.
Where Resource is an abstract.
and bind them with
install(new FactoryModuleBuilder().implement(Resource.class,
MyResource.class).build(
ResourceFactory.class));
Is it possible to bind like this?.
