All Implemented Interfaces:

java.beans.BeanInfo

public abstract class JJackBeanInfoAbstract
extends java.beans.SimpleBeanInfo

Abstract base class for BeanInfo classes describing JJack clients as JavaBeans. If a JJack client is a subclass of JJackMonitor or JJackClient, it can be used as a JavaBean. This class makes it easy to create the corresponding BeanInfo class.
