Hi Syd,
your code samples are not valid Java (well, the first one could be if
testVar would be a field, but that's unsafe instead maybe use
`AtomicReference` and `set` it from the completion?).
OnComplete has a `void` method so you cannot return from it.
Instead of taking things out of the future like this you can either:
1) keep mapping (transfroming the value):
future.map(new Function1<Object, Object>(){
@Override public Object apply(Object v1) {
return null;
}
}, ec);
never getting out of this transformation - this way you can chain all
transformations you need.
2) Await on the result of the future (*we discourage this*) as it will
block the thread that you're calling await from:
Future<Object> future = null;
Object o = scala.concurrent.Await.result(future, Duration.apply(100,
TimeUnit.DAYS))
Hope this helps, happy hakkionmg!
