/**
 * An iterator over a number of (filtered) partition.
 *
 * PartitionIterator is to RowIterator what UnfilteredPartitionIterator is to UnfilteredRowIterator
 * though unlike UnfilteredPartitionIterator, it is not guaranteed that the RowIterator
 * returned are in partitioner order.
 *
 * The object returned by a call to next() is only guaranteed to be
 * valid until the next call to hasNext() or next(). If a consumer wants to keep a
 * reference on the returned objects for longer than the iteration, it must
 * make a copy of it explicitely.
