public class TableMap
In a chain of data manipulators some behaviour is common. TableMap
provides most of this behaviour 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.
