overridevirtual |
Advance the loader by one iteration.
The function must pull an item from the underlying node, process it and return it. If the underlyng loader is exhausted, returns an empty optional.
Implements DataLoader.
|
overridevirtual |
Size of the loader, has value only for fixed cardinalities.
Implements DataLoader.
|
overridevirtual |
Reset the loader in order to restart the iteration.
Reimplemented from DataLoader.
