TableModel JDK 1.6)

Description

public interface TableModel

The TableModel interface specifies the methods the JTable will use to interrogate a tabular data model.

The JTable can be set up to display any data model which implements the TableModel interface with a couple of lines of code:

        TableModel myData = new MyTableModel(); 
        JTable table = new JTable(myData);

For further documentation, see Creating a Table Model in The Java Tutorial.

Methods

Hide/Show inherited methods

public void addTableModelListener (TableModelListener l)

Adds a listener to the list that is notified each time a change to the data model occurs.

public Class<Object> getColumnClass (int columnIndex)

Returns the most specific superclass for all the cell values in the column.

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.
Returns: the common ancestor class of the object values in the model.
Parameters:
- columnIndex - the index of the column

public int getColumnCount ()

Returns the number of columns in the model.

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.
Returns: the number of columns in the model
See Also: TableModel.getRowCount(),

public String getColumnName (int columnIndex)

Returns the name of the column at 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.
Returns: the name of the column
Parameters:
- columnIndex - the index of the column

public int getRowCount ()

Returns the number of rows in the model.

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.
Returns: the number of rows in the model
See Also: TableModel.getColumnCount(),

public Object getValueAt (int rowIndex, int columnIndex)

Returns the value for the cell at columnIndex and rowIndex.

Returns the value for the cell at columnIndex and
rowIndex.
Returns: the value Object at the specified cell
Parameters:
- rowIndex - the row whose value is to be queried
- columnIndex - the column whose value is to be queried

public boolean isCellEditable (int rowIndex, int columnIndex)

Returns true if the cell at rowIndex and columnIndex is editable.

Returns true if the cell at rowIndex and
columnIndex
is editable. Otherwise, setValueAt on the cell will not
change the value of that cell.
Returns: true if the cell is editable
Parameters:
- rowIndex - the row whose value to be queried
- columnIndex - the column whose value to be queried
See Also: TableModel.setValueAt(java.lang.Object, int, int),

public void removeTableModelListener (TableModelListener l)

Removes a listener from the list that is notified each time a change to the data model occurs.

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

Sets the value in the cell at columnIndex and rowIndex to aValue.

Sets the value in the cell at columnIndex and
rowIndex to aValue.
Parameters:
- aValue - the new value
- rowIndex - the row whose value is to be changed
- columnIndex - the column whose value is to be changed
