  • Constructor Details

    • CompletedFuture

      public CompletedFuture(V value, ExecutionException exception)
      Creates a CompletedFuture.

      If throwable is not null, the computation is deemed to have failed. The exception will be thrown (wrapped in a ExecutionException) when get() or get(long, java.util.concurrent.TimeUnit) are invoked.

      If exception is null, the computation is deemed to have succeeded. In this case, a null value in value just means that the computation yielded a null result.

      Parameters:
      value - Value (may be null)
      exception - Exception that occurred while computing result
