Repeats items coming from a nested loader. More...
Inheritance diagram for RepeatDataLoader:Repeats items coming from a nested loader.
Repetition can either by per epoch (i.e. the entire epoch of the nested data loader is repeated) or per item (i.e. each item is repeated a certain number of times) or both.

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.
|
overridevirtual |
Configure this object instance by de-serializing the given Properties.
The default implementation will do so automatically for all registered Parameter and SubProperty instances.
Reimplemented from DataLoader.
