| /** |
| * The "select" method retrieves all the entities for the input key list and sorts according to the user settings. Paging is taken into account when retrieving |
| * the results. The result is a list of the entity objects containing all top level elements (restricted to the given page). |
| * |
| * NOTE: Results usually need multiple one-to-many collections to be fetched. Although this could be done in one query with eager fetching, this strategy is not |
| * recommended as it will lead to a potentially large Cartesian product. Therefore, the collections are initialized in separate queries during the mapping |
| * stage. If the returned results are small (maxRows parameters is set appropriately), a single query is likely faster, but probably not by enough to consider |
| * the optimization under these conditions. |
