Class ProxyTableModel

java.lang.Object
  javax.swing.table.AbstractTableModel
      dsto.dfc.swing.table.AbstractDfcTableModel
          dsto.dfc.swing.table.ProxyTableModel

All Implemented Interfaces:

DfcTableModel, Serializable, EventListener, TableModelListener, TableModel

Direct Known Subclasses:

SortedTableModel

public class ProxyTableModel
extends AbstractDfcTableModel
implements DfcTableModel, TableModelListener

Generic base class for a table model that act as a proxy for another table model. All calls are by default forwarded to the enclosed table model, events are forwarded out (but with the source changed to the proxy).
