public abstract class CommonEditActionHandler<T extends java.awt.Component>
extends AbstractEditActionHandler

Abstract base class which takes care of some boilerplate for handling edit actions of Components. The canCopy(), canDelete(), and canPaste(Clipboard) methods return true when the injected component is the focus owner. The doCut() method essentially delegates to EditActionHandler.doCopy() and EditActionHandler.doDelete()
