NAME
__gnu_parallel::guarded_iterator -
SYNOPSIS
Detailed Description
template<typename RandomAccessIterator, typename Comparator> class __gnu_parallel::guarded_iterator< RandomAccessIterator, Comparator >
Iterator wrapper supporting an implicit supremum at the end of the sequence, dominating all comparisons.
The implicit supremum comes with a performance cost.
Deriving from RandomAccessIterator is not possible since RandomAccessIterator need not be a class.
