Inject superclass fields

[bookvarius]

I need to inject field which is declared in superclass.
For example:

class SuperSubject {
    @Inject
    private String field;

    ...
}

class SubSubject extends SuperSubject {
    ...
}

As I see you get declared fields of subject class only but not of all of it's superclasses.
What about to get all fields recursively?
E.g.

public static List<Field> getAllFields(List<Field> fields, Class<?> type) {
        fields.addAll(Arrays.asList(type.getDeclaredFields()));

        if (type.getSuperclass() != null) {
            fields = getAllFields(fields, type.getSuperclass());
        }

        return fields;
    }

...

List<Field> allFields = getAllFields(new ArrayList<Field>(), SubSubject.class);

Hi! :)

Sure - we can add this but the question is - why would you ever want to do that? I mean the whole idea of this extension is to deal with hopeless situations - and I understand that this is one of them? ;)

If you want to you can feel free to create a PR and if not then give me some time and I'll try to implement that.

I faced with such situation when injection is located in an abstract class (private field) and I need to test it's concrete implementation. I already solved this problem locally using some modification of your code. I tested it with field level DI only. It's just another use-case. So, if you think this can be helpful you can implement this. May be it will help others ;)

Maybe it will - I'm just thinking about the architectural issue here in your example

class SuperSubject {

    private final String field;

   SuperSubject(String field) {
    this.field = field
   }

    ...
}

class SubSubject extends SuperSubject {
    SubSubject(String field) {
    super(field)
    }
}

If the field is injected it should be injected through the constructor not through the field.

But anyway I understand that this tool is not supposed to heal the world but to inject that blody collaborator to a subject ;)
