Class AbstractTableModel

java.lang.Object
  nextapp.echo2.app.table.AbstractTableModel

All Implemented Interfaces:

java.io.Serializable, TableModel

Direct Known Subclasses:

DefaultTableModel

public abstract class AbstractTableModel

extends java.lang.Object

implements java.io.Serializable, TableModel

An abstract implementation of a TableModel. This class provides the following conveniences for TableModel implementation development:

• event listener management and notification
• a generic implementation of getColumnClass() which returns Object.class
• a generic implementation of getColumnName() which returns "spreadsheet-style" column names, i.e., A, B, C...Y, Z, AA, AB, AC....

AbstractTableModel()
Default constructor.

Method Summary

void	addTableModelListener(TableModelListener l) Adds a listener that will be notified of changes/
void	fireTableCellUpdated(int column, int row) Notifies TableModelListeners that the contents of the cell at the specified coordinate were changed.
void	fireTableChanged(TableModelEvent e) Notifies TableModelListeners of the specified event.
void	fireTableDataChanged() Notifies TableModelListeners that the content of the table (possibly including the number of rows) was changed, but that the table's structure has remained intact.

void	fireTableRowsInserted(int firstRow, int lastRow) Notifies TableModelListeners that the rows from firstRow to lastRow were inserted.
void	fireTableRowsUpdated(int firstRow, int lastRow) Notifies TableModelListeners that the data in the rows from firstRow to lastRow was updated.
void	fireTableStructureChanged() Notifies TableModelListener that all data in the table may have changed, including the size and structure of the table.
java.lang.Class	getColumnClass(int column) Returns Object.class
java.lang.String	getColumnName(int column) Returns column names using a "spreadsheet-style" convention, i.e., A, B, C...Y, Z, AA, AB, AC...
