E
- the type of the ListModel elementspublic abstract class AbstractTableAdapter<E> extends AbstractTableModel implements ListModelBindable
TableModel
interface that converts a ListModel
of row elements.
This class provides default implementations for the TableModel
methods #getColumnCount()
and #getColumnName(int)
.
To use these methods you must use the constructor that accepts an
array of column names and this array must not be null
.
If a subclass constructs itself with the column names set to null
it must override the methods #getColumnCount()
and
#getColumnName(int)
.
Example: API users subclass AbstractTableAdapter
and just implement the method TableModel#getValueAt(int, int)
.
The following example implementation is based on a list of customer rows and exposes the first and last name as well as the customer ages:
public class CustomerTableModel extends AbstractTableAdapter { public CustomerTableModel() { super("Last Name", "First Name", "Age"); } public Object getValueAt(int rowIndex, int columnIndex) { Customer customer = (Customer) getRow(rowIndex); switch (columnIndex) { case 0 : return customer.getLastName(); case 1 : return customer.getFirstName(); case 2 : return customer.getAge(); default: return null; } } }
