class SortedTupleIterator
- extends SortedIterator
A SortedTupleIterator is a modified SortedIterator. Whereas the sorted iterator
used by XSLT computes the sort key of each item in a sequence, using that item
as the context item, the SortedTupleIterator used by XQuery precomputes the sort
keys from scratch; they do not need to be a function of the item being sorted.
