| * JDBC ResultSet concurrency hint values. |
| * |
| * The class contains all the valid values for QueryHints.RESULT_SET_CONCURRENCY query hint. |
| * This can be used on ScrollableCursor queries to set the JDBC ResultSet concurrency. |
| * |
| * JPA Query Hint Usage: |
| * |
| * <p><code>query.setHint(QueryHints.RESULT_SET_CONCURRENCY, ResultSetConcurrency.ForwardOnly);</code> |
| * <p>or |
| * <p><code>@QueryHint(name=QueryHints.RESULT_SET_CONCURRENCY, value=ResultSetConcurrency.ForwardOnly)</code> |
| * |
| * <p>Hint values are case-insensitive. |
| * "" could be used instead of default value ResultSetConcurrency.Updatable. |
