An RWDBStatus that is a future object can be produced directly by some of the asynchronous functions listed in Section 12.7, or by the status method of any other future object. The following behavior applies to all RWDBStatus future objects.
This call will block since it can be answered only after completion of the asynchronous call:
bool RWDBStatus::isValid() |
This call will not block. If the asynchronous call has not completed, the returned status will be RWDBStatus::notReady.
RWDBStatus::ErrorCode RWDBStatus::errorCode() |
All the other methods of RWDBStatus will not block; however, they won't return meaningful messages either.
