[Insight-developers] changes to ProcessObject

[M.Staring at lumc.nl]

Hi all, Gaetan,

This commit:

http://itk.org/gitweb?p=ITK.git;a=commitdiff;h=322cb3952a45cbdb4a100a3d308769a6027d4f95

changed the function ProcessObject::UpdateOutputData. Notably a try-catch was changed from

try
      {
      this->GenerateData();
      }
    catch( ProcessAborted & excp )
      {
      this->InvokeEvent( AbortEvent() );
      this->ResetPipeline();
      this->RestoreInputReleaseDataFlags();
      throw excp;
      }
    catch( ExceptionObject& excp )
      {
      this->ResetPipeline();
     this->RestoreInputReleaseDataFlags();
      throw excp;
      }

to

try
    {
    this->GenerateData();
    }
  catch ( ProcessAborted & excp )
    {
    this->InvokeEvent( AbortEvent() );
    this->ResetPipeline();
    this->RestoreInputReleaseDataFlags();
    throw excp;
    }
  catch (...)
    {
    this->ResetPipeline();
    this->RestoreInputReleaseDataFlags();
    throw;
    }

So itk::ExceptionObject is not explicitely caught anymore.

In my code I depend on itk::ExceptionObject to be caught and re-thrown. I catch it again higher up, and do something with it (not just stopping the program). With this change the original throw (itkExceptionMacro) ends up in catch(...) and just "throw" is called instead of "throw excp". Is it possible to add an extra catch:

try
    {
    this->GenerateData();
    }
  catch ( ProcessAborted & excp )
    {
    this->InvokeEvent( AbortEvent() );
    this->ResetPipeline();
    this->RestoreInputReleaseDataFlags();
    throw excp;
    }
  catch( ExceptionObject & excp )
    {
    this->ResetPipeline();
    this->RestoreInputReleaseDataFlags();
    throw excp;
    }
  catch (...)
    {
    this->ResetPipeline();
    this->RestoreInputReleaseDataFlags();
    throw;
    }

?

which would restore the original working of my code.
