Class DowngradeActionMap

java.lang.Object
org.jfree.ui.action.DowngradeActionMap
public class DowngradeActionMap extends Object
An actionmap, which is JDK 1.2.2 compatible.

This implementation does not implement the ActionMap interface of JDK 1.3 or higher to maintain the compatibility with JDK 1.2 which does not know this interface.

The usage is still the same.
