* @brief The ArrayDataIteratorValue class represents the current value of an array data iterator. | ||||
* It offers standard access methods for the data in the series (at(), first()), but it is up to | ||||
* each array data to define its own implementation of how to retrieve this data (one-dim or two-dim | ||||
* array), by implementing the ArrayDataIteratorValue::Impl interface | ||||
