Class XJTable.SortingModel

java.lang.Object
  javax.swing.table.AbstractTableModel
      gate.swing.XJTable.SortingModel

All Implemented Interfaces:

Serializable, EventListener, TableModelListener, TableModel

Enclosing class:

XJTable

protected class XJTable.SortingModel
extends AbstractTableModel
implements TableModelListener

Handles translations between an indexed data source and a permutation of itself (like the translations between the rows in sorted table and the rows in the actual unsorted model).

Constructor Detail

XJTable.SortingModel

public XJTable.SortingModel(TableModel sourceModel)

Method Detail

init

protected void init(TableModel sourceModel)

tableChanged

public void tableChanged(TableModelEvent e)

This gets events from the source model and forwards them to the UI

Specified by:

tableChanged in interface TableModelListener

getRowCount

public int getRowCount()

Specified by:

getRowCount in interface TableModel

getColumnCount

public int getColumnCount()

Specified by:

getColumnCount in interface TableModel

getColumnName

public String getColumnName(int columnIndex)

Specified by:

getColumnName in interface TableModel

Overrides:

getColumnName in class AbstractTableModel

getColumnClass

public Class getColumnClass(int columnIndex)

Specified by:

getColumnClass in interface TableModel

Overrides:

getColumnClass in class AbstractTableModel

isCellEditable

public boolean isCellEditable(int rowIndex,
                              int columnIndex)

Specified by:

isCellEditable in interface TableModel

Overrides:

isCellEditable in class AbstractTableModel

setValueAt

public void setValueAt(Object aValue,
                       int rowIndex,
                       int columnIndex)

Specified by:

setValueAt in interface TableModel

Overrides:

setValueAt in class AbstractTableModel

getValueAt

public Object getValueAt(int row,
                         int column)

Specified by:

getValueAt in interface TableModel

sort

public void sort()

Sorts the table using the values in the specified column and sorting order. sortedColumn is the column used for sorting the data. ascending is the sorting order.

sourceToTarget

public int sourceToTarget(int index)

Converts an index from the source coordinates to the target ones. Used to propagate events from the data source (table model) to the view.

Parameters:

index - the index in the source coordinates.

Returns:

the corresponding index in the target coordinates or -1 if the provided row is outside the permitted values.

targetToSource

public int targetToSource(int index)

Converts an index from the target coordinates to the source ones.

Parameters:

index - the index in the target coordinates. Used to propagate events from the view (e.g. editing) to the source data source (table model).

Returns:

the corresponding index in the source coordinates or -1 if the row provided is outside the allowed range.

buildTargetToSourceIndex

protected void buildTargetToSourceIndex()

Builds the reverse index based on the new sorting order.
