public class Spin extends java.lang.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 interfaceBean
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 onbean
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.- See Also:
