Table - Storing data in a AbstractTableModel for a renderer

Question

I have a class which extends AbstractTableModel in which I am storing more than just the data which is displayed in each cell (i.e. metadata and other data which is specific to the cells are stored in private arrays).
I also have a class which extends DefaultTableCellRenderer which colorises the cells. There are several tables and they all use the same class to do the rendering however I would like it if I could retreive the data from the TableModel class to decide on the color of a cell . If I have:
private class calTableModel extends AbstractTableModel{
          public calTableModel() {
....Usual stuff
public int AnotherMethod(){...}
and I try this
private class CustomTableCellRenderer extends DefaultTableCellRenderer
          public Component getTableCellRendererComponent
          (JTable table, Object value, boolean isSelected,
          boolean hasFocus, int row, int column)
table.getModel().AnotherMethod()
then I get a cannot resolve symbol error.
How do I extend the interface as well as the class so I can call my other methods in this way?
Many thanks in advance.

Answer 1

You have to cast to your tableModel:private class CustomTableCellRenderer extends DefaultTableCellRenderer
public Component getTableCellRendererComponent
(JTable table, Object value, boolean isSelected,
boolean hasFocus, int row, int column)
((calTableModel )table.getModel()).AnotherMethod(); // cast to calTableModel
