AbstractTableModel, NewTableModel

Changes

1. subclass NewTableModel of AbstractTableModel.
2. NewTableModel.getRowCount implements AbstractTableModel.getRowCount .
3. NewTableModel.getRowCount returns the number of records available in the data source.
4. NewTableModel.getRecord implements AbstractTableModel.getRecord .
5. NewTableModel.getRecord returns the record that was demanded.
6. NewTableModel registers as a listener to its data source in order to be able to inform the JTable of any changes in the data source.
7. NewTable implements sorting and (optionally) filtering of the records in its data source.

Constraints

• The data to be visualized must be easily viewed as a list of records to fit the concepts behind util.swing.AbstractTableModel . If it does not, consider deriving your new model from javax.swing.table.TableModel directly.
