[google-appengine] How to get the result from DeferredTask ?

[J.Ganesan]

Hi,

At the end of run method of a DeferredTask, I have to notify an object to 
extract the result of run() method. How do I do that ?

// Not Serializable
public class DeferredTaskTrigger
{
  protected int resultAggregate_ = 0 ;

  protected void addToQueue()
  {  
    Queue queue = QueueFactory.getDefaultQueue() ;
    DeferredTaskTrial1 deferredTaskTrial1 = new DeferredTaskTrial1() ;
    TaskOptions taskOptions = 
TaskOptions.Builder.withPayload(deferredTaskTrial1) ;   
    TaskHandle taskHandle = queue.add(taskOptions) ;      
  }
  // This object calls addToQueue() hundreds of times and accumulates the 
results of  DeferredTaskTrial1 objects in resultAggregate_ .
}

public class DeferredTaskTrial1 implements DeferredTask
{
  protected int result_ = 0 ;
  
  public void run()
  {
    // processing code here.
    // .....

    // capture the result of processing.
    result_  = 1 ;
    
   //  how to get the reference of DeferredTaskTrigger here ? ( Apparently, 
no way.)
   //  how else I can notify the DeferredTaskTrigger object to extract the 
result_  ?
  }

}

Thanks
