Class MapTableModel

java.lang.Object

javax.swing.table.AbstractTableModel

org.crosswire.common.swing.MapTableModel

All Implemented Interfaces:

Serializable, TableModel

public class MapTableModel
extends AbstractTableModel

TableModel using a Map internally. Note that an AbstractTableModel (this is-a AbstractTableModel) reports changes to the data to the table itself. However since a Map does not have a addChangeListener interface we can't do the same - SO if you change the Map while we are displaying it then don't expect the changes to be automatically reflected in the JTable.
