Returns the cause of the failed I/O operation if the I/O operation has failed.- Returns:
- the cause of the failure.

Waits for this future until it is done, and rethrows the cause of the failure if this future failed. -
syncUninterruptibly
Description copied from interface:Future
Waits for this future until it is done, and rethrows the cause of the failure if this future failed.- Specified by:

getNow
Description copied from interface:Future
Return the result without blocking. If the future is not done yet this will returnnull
. As it is possible that anull
value is used to mark the future as successful you also need to check if the future is really done withFuture.isDone()
and not rely on the returnednull
value.
