Method Detail

getColumnCount

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.

Returns:

the number of columns in the model

getColumnClass

java.lang.Class<?> getColumnClass(int columnIndex)

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.

Parameters:

columnIndex - the index of the column

Returns:

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

getColumnName

java.lang.String getColumnName(int 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.

Parameters:

columnIndex - the index of the column

Returns:

the name of the column

getValueAt

java.lang.Object getValueAt(T rowValue,
                          int columnIndex)

Returns the value for the cell at columnIndex and rowIndex.

Parameters:

rowValue - the object representing the row

columnIndex - the column whose value is to be queried

Returns:

the value Object at the specified cell

setValueAt

void setValueAt(T rowValue,
              java.lang.Object value,
              int columnIndex)

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

Parameters:

rowValue - the object representing the row

value - the new value

columnIndex - the column whose value is to be changed

isCellEditable

boolean isCellEditable(T rowValue,
                     int columnIndex)

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

Parameters:

rowValue - the object representing the row

columnIndex - the column being queried

Returns:

false
