Examples of org.apache.pig.data.SortedDataBag$SortedDataBagIterator

org.apache.pig.data.SortedDataBag
An iterator that handles getting the next tuple from the bag. This iterator has a couple of issues to deal with. First, data can be stored in a combination of in memory and on disk. Second, the bag may be asked to spill while the iterator is reading it. This means that it will be pointing to someplace in memory and suddenly it will need to switch to a disk file.

    private void accumulateData() throws ExecException {
  int size = inputs.size();
  its = new Iterator[size];
  data = new Tuple[size];
  for(int i = 0; i < size; i++) {
      DataBag bag = new SortedDataBag(new groupComparator());
      for(Result input = inputs.get(i).getNext(dummyTuple); input.returnStatus != POStatus.STATUS_EOP; input = inputs.get(i).getNext(dummyTuple)) {
          if(input.returnStatus == POStatus.STATUS_ERR) {
              throw new ExecException("Error accumulating output at local Cogroup operator");
          }
          if(input.returnStatus == POStatus.STATUS_NULL)
              continue;
          bag.add((Tuple) input.result);
      }
      
      its[i] = bag.iterator();
      data[i] = its[i].next();
  }
