Examples of org.apache.pig.data.DefaultDataBag$DefaultDataBagIterator

org.apache.pig.data.DefaultDataBag
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.

                columns.add(columnToTuple(entry.getKey(), entry.getValue()));

            tuple.set(1, new DefaultDataBag(columns));
            return tuple;
