Injecting Collection of Classes with Guice

Question

I\'m trying to inject things with Google Guice 2.0 and I have the following structure:

FooAction implements Action
BarAction implements Action

Answer 1

What you want for this is Multibindings. Specifically, you want to bind a Set (not a List, but a Set is probably what you really want anyway) like this:

Multibinder actionBinder = Multibinder.newSetBinder(binder(), Action.class);
actionBinder.addBinding().to(FooAction.class);
actionBinder.addBinding().to(BarAction.class);

Then you can @Inject the Set anywhere.
