Business Process Modeling and Analysis

In release 1.1 of the Java Development Kit (JDK 1.1) a new event-handling model was introduced. This model was called the Delegation Event Model. Although it is extensively used in the Abstract Window Toolkit (AWT) of the JDK, it was originally designed for the JavaBeans architecture. It is the mechanism by which one bean informs another bean that something has happened or that it wants that bean to perform some action. It is therefore very important to understand how the Delegation Event Model works. This chapter provides an introduction to this event-handling model — if you are already familiar with it you may wish to move on to the next chapter.
