Class Spin

java.lang.Object
spin.Spin
public class Spin extends Object

Spin offers a transparent threading solution for developing non-freezing Swing applications.

Let bean be a reference to a non-visual (possibly multithreaded) bean implementing the interface Bean whose methods have to be called by a Swing component. You can avoid any freezing by using one line of code: 

 bean = (Bean) Spin.off(bean);
Now each method call on bean is executed on a separate thread, while the EDT is continuing to dispatch events. All return values or exceptions are handled by Spin and transparently returned to the calling method.

For calls from other threads than the EDT to your Swing component you can use the following (being XYListener any interface your component implements): 

     bean.addXYListener((XYListener)Spin.over(component);
Now all required updates to your component (and/or its model) are transparently excuted on the EDT.
