Guice: Is it possible to get all instances with binding for a specific parent / interface / annotation?

Question

I know that this cannot be dependency injection in its purest form, but let's say I have to use:

@Inject Injector injector; 

Using this injector, you can get all related instances:

• A parent class that each instance would inherit from?
• The interface that each instance will implement?
• Annotations that each instance would have?

I see the Injector # findBindingsByType () method, but I'm not sure if it can help in this regard.

You can enter a list of a given type, linked using multi-exchange. Check documents:
