/**
|
|
* This class is used to implement a chain of event handlers. Dispatching
|
|
* using this class is thread safe. Here is a quick example of how to
|
|
* add and delete listeners using this class. For this example, we will
|
|
* assume are firing <code>AdjustableEvent</code>'s. However, this
|
|
* same approach is useful for all events in the <code>java.awt.event</code>
|
|
* package, and more if this class is subclassed.
|
|
* <p>
|
|
* <code>
|
|
* AdjustmentListener al;
|
|
*
|
|
* public void
|
|
* addAdjustmentListener(AdjustmentListener listener)
|
|
* {
|
|
* al = AWTEventMulticaster.add(al, listener);
|
|
* }
|
|
*
|
|
* public void
|
|
* removeAdjustmentListener(AdjustmentListener listener)
|
|
* {
|
|
* al = AWTEventMulticaster.remove(al, listener);
|
|
* }
|
|
* </code>
|
|
* <p>
|
|
* When it come time to process an event, simply call <code>al</code>,
|
|
* assuming it is not <code>null</code>.
|
|
* <p>
|
|
* The first time <code>add</code> is called it is passed
|
|
* <code>null</code> and <code>listener</code> as its arguments. This
|
|
* starts building the chain. This class returns <code>listener</code>
|
|
* which becomes the new <code>al</code>. The next time, <code>add</code>
|
|
* is called with <code>al</code> and <code>listener</code> and the
|
|
* new listener is then chained to the old.
