---

setSortColumns

public void setSortColumns(int primary,
                           int secondary)

---

pushSortColumn

public void pushSortColumn(int column)

---

setPrimarySortColumn

public void setPrimarySortColumn(int column)

---

getPrimarySortColumn

public int getPrimarySortColumn()

---

setSecondarySortColumn

---

isReversed

public boolean isReversed()

---

getRowCount

public int getRowCount()

Description copied from interface: javax.swing.table.TableModel

Returns the number of rows in the model.

---

getColumnCount

public int getColumnCount()

Description copied from interface: javax.swing.table.TableModel

Returns the number of columns in the model.

---

getColumnName

public java.lang.String getColumnName(int column)

Description copied from class: javax.swing.table.AbstractTableModel

Returns the name of the specified column. This method generates default names in a sequence (starting with column 0): A, B, C, ..., Z, AA, AB, AC, ..., AZ, BA, BB, BC, and so on. Subclasses may override this method to allow column names to be specified on some other basis.

---

getColumnClass

public java.lang.Class getColumnClass(int column)

Description copied from class: javax.swing.table.AbstractTableModel

Returns the Class for all Object instances in the specified column.

---

isCellEditable

public boolean isCellEditable(int row,
                              int column)

Description copied from class: javax.swing.table.AbstractTableModel

Returns true if the specified cell is editable, and false if it is not. This implementation returns false for all arguments, subclasses should override the method if necessary.

---

getValueAt

public java.lang.Object getValueAt(int row,
                                   int column)

Description copied from interface: javax.swing.table.TableModel

Returns the value (Object) at a particular cell in the table.

---

setValueAt

public void setValueAt(java.lang.Object aValue,
                       int row,
                       int column)

Description copied from class: javax.swing.table.AbstractTableModel

Sets the value of the given cell. This implementation ignores all arguments and does nothing, subclasses should override the method if necessary.

---

toRealIndex

public int toRealIndex(int sorted)

Maps an index in the sorted view to an index in the real table.

---

toSortedIndex

public int toSortedIndex(int real)

Maps an index in the real table to an index in the sorted view.

---

resetIndexMap

protected void resetIndexMap()

Creates a new identity mapping.

---

resortTable

protected boolean resortTable()

Recalculates the sorted view and returns true if the view has changed.
