| 36 | * In a chain of data manipulators some behaviour is common. TableMap |
| 37 | * provides most of this behavour and can be subclassed by filters |
| 38 | * that only need to override a handful of specific methods. TableMap |
| 39 | * implements TableModel by routing all requests to its model, and |
| 40 | * TableModelListener by routing all events to its listeners. Inserting |
| 41 | * a TableMap which has not been subclassed into a chain of table filters |
| 42 | * should have no effect. |
