@Doug – I don’t believe you can do that (at least without ugly hacks like changing the “final” property of the field with reflection). Assisted injection is just a shortcut – if you can’t achieve this via a full-fledged Factory class, then assisted injection won’t help you.

Try asking on Stack Overflow though, there might be something I missed.

Can you show how to use this assist technique to set a final variable?

As far as I can tell, Guice uses constructors that DO NOT set the final variable (because your build() method will set it). But if your constructor doesn’t set the final variable, the compiler stops you.

How are you getting around not having a constructor set the final variable?

@Ken – you’re right, .Net has come a long way in the last few years.
Nice to see this use case for anonymous classes. I should really try out scala some time.

you only need … factory … annotate… tell guice…

sigh

Java is so tiresome even with reasonably good tooling.

.NET frameworks allow stuff like .Resolve(new{numberOfRetries=3}) and really be done with it. I’d bet that scala would support it
