er.extensions.eof.ERXFetchSpecificationBatchIterator.nextBatch()
Gets the next batch of enterprise objects for the given fetch specification. Note that the editing context that is set will be used to fetch against. You can swap out a different editing context before calling this method to reduce memory consumption. (However, if you are mixing calls to this method with calls to {@link #next()} or {@link #nextElement()}, this method may return a partial batch of already-cached objects, in the editing context which was in place at the time they were fetched.) @return batch of enterprise objects

      ERXFetchSpecificationBatchIterator fsIterator = new ERXFetchSpecificationBatchIterator(fs, ec);


      // Loop for a period of time
      while (fsIterator.hasNext() && !_isStopped) {
        @SuppressWarnings("unchecked")
        NSArray<ResultItem> batch = fsIterator.nextBatch();
        
        for (ResultItem resultItem : batch) {
          resultItem.setWorkflowState(ResultItem.WORKFLOW_CHECKING_FACTORIAL);
          performFactorialProcessing(resultItem);
          resultItem.setWorkflowState(ResultItem.WORKFLOW_PROCESSING_COMPLETE);
