[cdt-dev] DSF - use of asynchronous method to retrieve informations in D

[Maherzia BELAAZI <maherzia.belaazi@xxxxxx>]

Hello,

 

I’m calling an asynchronous method that uses a DataRequestMonitor. This method returns a set of variables

Calling this method in Run mode : I get empty set

Calling this method in debug mode and stepping in : I get a set with correct values

So in Run mode i used “Thread.sleep” to solve a problem of conflict between threads (a simple reflection)

But it is not a good solution

My question is

how could I complete an asynchronous method call and get returned values without setting a Thread.sleep ?                                                                                         

 

                                                                                                                                                             

 

My piece of code :

final ArrayList<IExpressionDMContext> children = new ArrayList<IExpressionDMContext>();

IExpressions expressionService = fServicesTracker.getService(IExpressions.class, null);

DataRequestMonitor<IExpressionDMContext[]> drm =  // the used DataRequestMonitor

                           new DataRequestMonitor<IExpressionDMContext[]>(fSession.getExecutor(), rm) {

                                  protected void handleSuccess() {

                                        children.addAll(Arrays.asList(getData())); (1)

                                        //children here are not empty

                                  }

 

                           };

expressionService.getSubExpressions(miDMCExp, drm);     // call of the asynchronous method

//children here are empty

 

In handleSuccess() method normally (as I understood) the calling of the asynchronous  method is completed.

And so in (1) I get all searched data.

But in (2) the filled “children” is empty.

 

Is there any wrong use the asynchronous  method ? is something missing ?

 

Thanks for any help
