Package spin

Class Spin

java.lang.Object

spin.Spin

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 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.

            Evaluator evaluator)

Create a Spin wrapper for the given object.

Parameters:

object - object to wrap

evaluator - evaluator of invocations on the given object

Spin

public Spin(java.lang.Object object,
            ProxyFactory proxyFactory,
            Evaluator evaluator)

Create a Spin wrapper for the given object.

Parameters:

The returned object can safely be casted to any interface the wrapped object implements.

Returns:

the new proxy

off

public static java.lang.Object off(java.lang.Object object)

Convenience method to spin-off the given object from Swing.

The returned object can safely be casted to any interface the given object implements.

Parameters:

object - the object to spin-off

Returns:

proxy for the given object

over

public static java.lang.Object over(java.lang.Object object)

Convenience method to spin-over the given object with Swing.
The returned object can safely be casted to any interface the given object implements.

Parameters:

object - the object to spin-over

Returns:

proxy for the given object
