Class TableMap

java.lang.Object

javax.swing.table.AbstractTableModel

net.sf.cuf.ui.table.TableMap

All Implemented Interfaces:

Serializable, EventListener, TableModelListener, TableModel

Direct Known Subclasses:

TableSorter

public class TableMap
extends AbstractTableModel
implements TableModelListener

In a chain of data manipulators some behaviour is common. TableMap provides most of this behavour and can be subclassed by filters that only need to override a handful of specific methods. 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.

Field Detail

mModel

Reference to the original table model.

Constructor Detail

TableMap

public TableMap()

Method Detail

getModel

public TableModel getModel()

Get the original table model.

Returns:

the original table model

setModel

public void setModel(TableModel pModel)

Set a new TableModel.

Parameters:

pModel - the new TableModel

getValueAt

public Object getValueAt(int pRow,
                int pColumn)

Returns the value for the cell at aColumn and aRow.

Specified by:

getValueAt in interface TableModel

Parameters:

pRow - the row whose value is to be queried

pColumn - the column whose value is to be queried

Returns:

the value Object at the specified cell

setValueAt

public void setValueAt(Object pValue,
              int pRow,
              int pColumn)

Sets the value in the cell at aColumn and aRow to aValue.

Specified by:

setValueAt in interface TableModel

Overrides:

setValueAt in class AbstractTableModel

Parameters:

pValue - the new value

pRow - the row whose value is to be changed

pColumn - the column whose value is to be changed

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.

Specified by:

getRowCount in interface TableModel

Returns:

the number of rows in the model

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.

Specified by:

getColumnCount in interface TableModel

Returns:

the number of columns in the model

getColumnName

public String getColumnName(int pColumn)

Returns the name of the column at aColumn. 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.

Specified by:

getColumnName in interface TableModel

Overrides:

getColumnName in class AbstractTableModel

Parameters:

pColumn - the index of the column

Returns:

the name of the column

getColumnClass

public Class getColumnClass(int pColumn)

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.

Specified by:

getColumnClass in interface TableModel

Overrides:

getColumnClass in class AbstractTableModel

Parameters:

pColumn - the index of the column

Returns:

the common ancestor class of the object values in the model.

isCellEditable

public boolean isCellEditable(int pRow,
                     int pColumn)

Returns true if the cell at row and column is editable. Otherwise, setValueAt on the cell will not change the value of that cell.

Specified by:

isCellEditable in interface TableModel

Overrides:

isCellEditable in class AbstractTableModel

Parameters:

pRow - the row whose value to be queried

pColumn - the column whose value to be queried

Returns:

true if the cell is editable

tableChanged

public void tableChanged(TableModelEvent pEvent)

This fine grain notification tells listeners the exact range of cells, rows, or columns that changed.

Specified by:

tableChanged in interface TableModelListener

Parameters:

pEvent - the TableModelEvent containing notification
