      • CompletedFuture

        public CompletedFuture​(V value,
                               java.util.concurrent.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

      • success

        public static <T> CompletedFuture<T> success​(T t)

        Parameters:
        t - Result of computation
        Returns:
        Completed future that will yield the result
      • fail

        public static <T> CompletedFuture<T> fail​(java.lang.Throwable e)
        Creates a completed future indicating failure.
        Parameters:
        e - Exception
        Returns:
        Completed future that will throw
