How to identify whether a row has been modified or not

There is an easy way to find whether a row has been modified/deleted/created in ADF framework, This works only for Entity based view objects which are based on entity object.

      Iterator tbiter =
        EmployeeEOImpl.getDefinitionObject().getAllEntityInstancesIterator(getDBTransaction());
      while (tbiter.hasNext())
      {
        
EmployeeEOImpl eoImpl = (EmployeeEOImpl) tbiter.next();
        if (eoImpl.getEntityState() == Entity.STATUS_NEW ||
            eoImpl.getEntityState() == Entity.STATUS_MODIFIED ||
            eoImpl.getEntityState() == Entity.STATUS_DELETED)
        {

                  // Add your logic here
        }
