Method Summary
`void` | `onComplete(java.util.concurrent.Future<T> f)` Invoked when a Future has reached the completed termination state.

Method Detail

### onComplete

    void onComplete(java.util.concurrent.Future<T> f)
                    throws java.lang.InterruptedException

  Invoked when a Future has reached the completed termination state.

  The catching of a `ExecutionException` when `Future.get` is invoked may be utilized to determine if the future terminated with an exception. The exception can be obtained by invoking `Throwable.getCause()`.

  The catching of a `CancellationException` when `Future.get` is invoked may be utilized to determine if the future terminated with a cancellation.

  Parameters:
    `f` - the completed Future. Invocation of `Future.isDone()` will return true. Since the future is complete invocation of `Future.get()` and `Future.get(long, java.util.concurrent.TimeUnit)` will not result in the throwing of an `InterruptedException`.
  Throws:
    `java.lang.InterruptedException` - this exception is declared so that the developer does not need to catch it when invoking `Future.get`.
