Class TristateCheckBox.TristateDecorator

java.lang.Object

org.catacomb.druid.swing.TristateCheckBox.TristateDecorator

All Implemented Interfaces:

java.awt.ItemSelectable, javax.swing.ButtonModel

Enclosing class:

TristateCheckBox

private class TristateCheckBox.TristateDecorator
extends java.lang.Object
implements javax.swing.ButtonModel

Exactly which Design Pattern is this? Is it an Adapter, a Proxy or a Decorator? In this case, my vote lies with the Decorator, because we are extending functionality and "decorating" the original model with a more powerful model.
