Class AbstractCellEditor

java.lang.Object

javax.swing.AbstractCellEditor

All Implemented Interfaces:

Serializable, CellEditor

Direct Known Subclasses:

DefaultCellEditor

public abstract class AbstractCellEditor
extends Object
implements CellEditor, Serializable

A base class for CellEditors, providing default implementations for the methods in the CellEditor interface except getCellEditorValue(). Like the other abstract implementations in Swing, also manages a list of listeners.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the java.beans package. Please see XMLEncoder.

Since:

1.3
