Class TableMap

java.lang.Object
  javax.swing.table.AbstractTableModel
      org.afcs.warts.gui.TableMap

All Implemented Interfaces:

java.util.EventListener, java.io.Serializable, javax.swing.table.TableModel, javax.swing.event.TableModelListener

Direct Known Subclasses:

TableModelRowColumnMap, TableSorter

public class TableMap

extends javax.swing.table.AbstractTableModel

implements javax.swing.event.TableModelListener

The TableMap class is an identity transformation for TableModels, and can be used as the basis for classes that wish to perform more complex transformations or mappings on TableModels.

TableMap implements TableModel by routing all requests to its model, and TableModelListener by routing all events to its listeners. Inserting a TableMap which has not been subclassed into a chain of table filters should have no effect.

This implementation is based on version 1.5 of Philip Milne's code (I can't find the original implementation, but google finds lots of other people using it), but has some minor major API changes.
