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