| * Defines strategies for fetching data from the database. |
| * The <code>EAGER</code> strategy is a requirement on the persistence |
| * provider runtime that data must be eagerly fetched. The |
| * <code>LAZY</code> strategy is a hint to the persistence provider |
| * runtime that data should be fetched lazily when it is |
| * first accessed. The implementation is permitted to eagerly |
| * fetch data for which the <code>LAZY</code> strategy hint has been |
| * specified. |
