public abstract class JvAbstractObjectTableModel
extends AbstractTableModel
implements JvObjectTableModel

A JvObjectTableModel is a TableModel in which each row is actually a single object (which implements JvObjectTableRow. The columns of a row typically represent different fields of the row object.

Field Detail

rowData

protected List rowData

The List of JvObjectTableRow objects.

Constructor Detail

JvAbstractObjectTableModel

public JvAbstractObjectTableModel()

Construct a JvObjectTableModel with the given row data.

Method Detail

getRowAt

protected abstract JvObjectTableRow getRowAt(int row)

Return the JvObjectTableRow for the specified row.

Parameters:

row - the index of the desired row

Returns:

the JvObjectTableRow for the specified row

getObjectAt

public Object getObjectAt(int row)

Return the domain object associated with the specified row.

Specified by:

getObjectAt in interface JvObjectTableModel

Parameters:

row - the index of the desired row

Returns:

the domain object for the specified row

getEmptyCollection

public Collection getEmptyCollection()

Return an empty collection suitable for putting the selected items within.

Specified by:

getEmptyCollection in interface JvObjectTableModel

Returns:

an empty ArrayList

getColumnCount

public int getColumnCount()

Returns 0 for the number of columns in this data table. This method returns 0 because the TableColumnModel should not be created from this TableModel. Columns should be created using the JvSwingFactory.createTableColumn(javax.swing.JTable, java.lang.String, int) method.

Specified by:

getColumnCount in interface TableModel

Returns:

0

getColumnClass

public Class getColumnClass(int columnIndex)

Return the class of object displayed in the specified column. This method makes a guess at the class by querying the row data. If there is no row data, Object is returned.

Specified by:

getColumnClass in interface TableModel

Overrides:

getColumnClass in class AbstractTableModel

Parameters:

columnIndex - the column being queried

Returns:

the class of the object of the specified column

getValueAt

public Object getValueAt(int row,
                         int column)

Returns an attribute value for the cell at row and column.

Specified by:

getValueAt in interface TableModel

Parameters:

row - the row whose value is to be queried

column - the column whose value is to be queried

Returns:

the value Object at the specified cell

setValueAt

public void setValueAt(Object value,
                       int row,
                       int column)

Sets the object value for the cell at column and row. value is the new value. This method will generate a tableChanged notification.

Specified by:

setValueAt in interface TableModel

Overrides:

setValueAt in class AbstractTableModel

Parameters:

value - the new value; this can be null

row - the row whose value is to be changed

column - the column whose value is to be changed

isCellEditable

public boolean isCellEditable(int row,
                              int column)

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:

row - the row whose value to be queried

column - the column whose value to be queried

Returns:

true if the cell is editable
