Class AsyncWorker

java.lang.Object

foxtrot.AsyncWorker

public class AsyncWorker
extends Object

The class that executes asynchronous tasks.
This class is used when asynchronous task processing is needed, while Worker is normally used for synchronous task processing. This class offers a functionality similar to what provided by Sun's SwingWorker . Example usage:

 final JButton button = new JButton("Send a message !");
 button.addActionListener(new ActionListener()
 {
    public void actionPerformed(ActionEvent e)
    {
       AsyncWorker.post(new AsyncTask()
       {
          public Object run() throws Exception
          {
             // Send some long message
             Thread.sleep(10000);
             return null;
          }
 

          public void finish()
          {
             // Check to see if there are exceptions
             // by calling getResultOrThrow()
             try
             {
                getResultOrThrow();
                button.setText("Message sent !");
             }
             catch (Exception x)
             {
                // Report exception to the user, or just log it
             }
          }
       });
    }
 });
