Class SortableTableModel

java.lang.Object
  javax.swing.table.AbstractTableModel
      javax.swing.table.DefaultTableModel
          nl.cwi.sen1.visplugin.table.model.SortableTableModel

All Implemented Interfaces:

java.io.Serializable, javax.swing.table.TableModel

public class SortableTableModel
extends javax.swing.table.DefaultTableModel

Table model supporting column sortings. This model is able to work directly with RTuples and its data should be set using the setRTupleData() function. The original RElems can then be retrieved for every table row using the getRElemForRow() function.

                         boolean isAscent)

Retrieve the value for a given postion (row,col).

Parameters:

column - the column to base the sort on

isAscent - ascending (true) or or decending (false) order

getIndexes

public int[] getIndexes()

Returns the index mapping on which the current sort is based.
