com.jgoodies.binding.extras
Class DelegatingTableModel  

java.lang.Object
  javax.swing.table.AbstractTableModel
      com.jgoodies.binding.extras.DelegatingTableModel

All Implemented Interfaces:

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

---

public final class DelegatingTableModel

extends javax.swing.table.AbstractTableModel

This implementation of the TableModel interface delegates all requests to an underlying TableModel delegate. It can be used to change a JTable's model while the table is beeing displayed.

Note: This class is not yet part of the binary Binding library; it comes with the Binding distributions as an extra. The API is work in progress and may change without notice; this class may even be completely removed from future distributions. If you want to use this class, you may consider copying it into your codebase.

Field Detail

delegateChannel

private final ValueModel delegateChannel

Holds a model that in turn holds the delegated TableModel.

Constructor Detail

DelegatingTableModel

public DelegatingTableModel(ValueModel delegateChannel)

Constructs a TableAdaptor that holds the delegated TableModel in the given delegate channel.

---

DelegatingTableModel

public DelegatingTableModel()

Constructs a TableAdaptor on a dummy TableModel.

Method Detail

getDelegate

public javax.swing.table.TableModel getDelegate()

Returns the current TableModel delegate.

---

setDelegate

public void setDelegate(javax.swing.table.TableModel newDelegate)

Sets a new TableModel delegate.

---

getColumnClass

public java.lang.Class getColumnClass(int columnIndex)

Returns the most specific superclass for all the cell values in the column. This is used by the JTable to set up a default renderer and editor for the column.

---

getColumnCount

public int getColumnCount()

Returns the number of columns in the model. A JTable uses this method to determine how many columns it should create and display by default.

---

getColumnName

public java.lang.String getColumnName(int columnIndex)

Returns the name of the column at columnIndex. This is used to initialize the table's column header name. Note: this name does not need to be unique; two columns in a table can have the same name.

---

getRowCount

public int getRowCount()

Returns the number of rows in the model. A JTable uses this method to determine how many rows it should display. This method should be quick, as it is called frequently during rendering.

---

getValueAt

public java.lang.Object getValueAt(int rowIndex,
                                   int columnIndex)

Returns the value for the cell at columnIndex and rowIndex.
