class Response[T] extends AnyRef

Typical interaction, given a predicate <user-input>, a function <display>, and an exception handler <handle>:

val TIMEOUT = 100 // (milliseconds) or something like that val r = new Response() while (!r.isComplete && !r.isCancelled) { if (<user-input>) r.cancel() else r.get(TIMEOUT) match { case Some(Left(data)) => <display>(data) case Some(Right(exc)) => <handle>(exc) case None => } }
