Non-generic Retryer? about guava-retrying HOT 4 OPEN

Somewhat related, isn't a "generic callable" more like a Runnable? I would like to have support for giving a Runnable, but that would probably also require some refactoring to have different types of Retryers.

I think I was thinking more along the lines of RunnableFuture. The idea is that I would like to build a single retryer that works for any number of callables with arbitrary return types. This would probably lose out on the ability to retry on a specific return value. I took a pass at it, but Java's type system (and type erasure) made it really annoying to implement cleanly.

Full disclosure, I no Java expert.

@jalaziz I see. Did you try to use a Callable<Object> and do type checking of the result? Would that work?

from guava-retrying.

It would, but it sacrifices type safety and is less convenient (having to cast every result would be a pain). It's not that much of a concern anymore, though, as I've started transitioning to Scala where this type of thing is much easier to do.
