@ParametersAreNonnullByDefault public interface ManyValueWithLists extends ManyValueMapper
ManyValueMapper that provides a default behavior to represent the "multi-valued" characteristic as Lists. The implementation used is specified by the getOrCreateList(SingleFeatureBean) method.
Using a List-based implementation allows to benefit from the rich Java Collection API, with
the cost of a small memory overhead compared to raw arrays.
| Modifier and Type | Method and Description |

List to store the multi-valued features identified by the feature.
By default, this method creates an ArrayList which favor random read access method, to the detriment of
insertions and deletions.
