UNAVAILABLE
The subtask result or exception is not available. This state indicates that the subtask was forked but has not completed, it completed after the scope was cancelled, or it was forked after the scoped was cancelled (in which case a thread was not created to execute the subtask). -
SUCCESS
The subtask completed successfully. TheSubtask.get()PREVIEW method can be used to get the result. This is a terminal state. -
FAILED
The subtask failed with an exception. TheSubtask.exception()PREVIEW method can be used to get the exception. This is a terminal state.
