Clear cache issue!

Hi All,



            I'm using the following code:



                        QueryByCriteria queryByCriteria =

                        new QueryByCriteria(RefInfoData.class, criteria,
true);



            broker.clearCache();

            

            Collection refInfo =

                        (Collection)
broker.getCollectionByQuery(queryByCriteria);   



            For the class 'RefInfoData' we have set the cache level as
default implementation.



            When we use the method "broker.clearCache()" we are facing
performance issues.

            But when we don't clear cache there is dirty read.

           

            We are maintaining the cache for reference tables.



            Is there a way to clear cache for the specific object
instead of whole cache?





Regards,

Vagula
