Class Job

java.lang.Object
  foxtrot.Task
      foxtrot.Job

Direct Known Subclasses:

FlushJob

public abstract class Job
extends Task

A time-consuming task to be executed in the Worker Thread that does not throw checked exceptions.
Users must implement the run() method with the time-consuming code:

 Job task = new Job()
 {
     public Object run()
     {
        long sum = 0;
        for (int i = 0; i < 1000000; ++i)
        {
           sum += i;
        }
        return new Integer(sum);
     }
 };
 

RuntimeExceptions or Errors thrown by the run() method will be rethrown automatically by Worker.post(Job) or ConcurrentWorker.post(Job).

Method Detail

run

public abstract Object run()

The method to implement with time-consuming code. It should NOT be synchronized or synchronize on this Job instance, otherwise the AWT Event Dispatch Thread cannot efficiently test when this Job is completed. Overridden to remove the throws clause, so that users does not have to catch unthrown exceptions.
