public void addTableModelListener(TableModelListener l) Adds a listener to the list that is notified each time a change to the data model occurs. Parameters l:TableModelListener the TableModelListener

addTableModelListener

back to summary

public void addTableModelListener(TableModelListener l)

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

Parameters

l:TableModelListener: the TableModelListener

getColumnClass back to summary

getColumnClass	back to summary
public 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:int the index of the column Returns:Class<?> the common ancestor class of the object values in the model.

public 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:int: the index of the column

Returns:Class<?>

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

getColumnCount back to summary

getColumnCount	back to summary
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. Returns:int the number of columns in the model See Also `getRowCount`

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.

Returns:int: the number of columns in the model
See Also: getRowCount

getColumnName back to summary

getColumnName	back to summary
public 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:int the index of the column Returns:String the name of the column

public 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:int: the index of the column

Returns:String

the name of the column

getRowCount back to summary

getRowCount	back to summary
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. Returns:int the number of rows in the model See Also `getColumnCount`

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.

Returns:int: the number of rows in the model
See Also: getColumnCount

getValueAt back to summary

getValueAt	back to summary
public Object getValueAt(int rowIndex, int columnIndex) Returns the value for the cell at `columnIndex` and `rowIndex`. Parameters rowIndex:int the row whose value is to be queried columnIndex:int the column whose value is to be queried Returns:Object the value Object at the specified cell

public Object getValueAt(int rowIndex, int columnIndex)

Returns the value for the cell at columnIndex and rowIndex.

Parameters

rowIndex:int: the row whose value is to be queried
columnIndex:int: the column whose value is to be queried

Returns:Object

the value Object at the specified cell

isCellEditable back to summary

isCellEditable	back to summary
public boolean isCellEditable(int rowIndex, 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 rowIndex:int the row whose value to be queried columnIndex:int the column whose value to be queried Returns:boolean true if the cell is editable See Also `setValueAt`

public boolean isCellEditable(int rowIndex, 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

rowIndex:int: the row whose value to be queried
columnIndex:int: the column whose value to be queried

Returns:boolean

true if the cell is editable

setValueAt

removeTableModelListener	back to summary
public void removeTableModelListener(TableModelListener l) Removes a listener from the list that is notified each time a change to the data model occurs. Parameters l:TableModelListener the TableModelListener

removeTableModelListener

back to summary

public void removeTableModelListener(TableModelListener l)

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

Parameters

l:TableModelListener: the TableModelListener

setValueAt back to summary

setValueAt	back to summary
public void setValueAt(Object aValue, int rowIndex, int columnIndex) Sets the value in the cell at `columnIndex` and `rowIndex` to `aValue`. Parameters aValue:Object the new value rowIndex:int the row whose value is to be changed columnIndex:int the column whose value is to be changed See Also `getValueAt`, `isCellEditable`

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

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

Parameters

aValue:Object: the new value
rowIndex:int: the row whose value is to be changed
columnIndex:int: the column whose value is to be changed
