bool operator< (_GuardedIterator< _RAIter, _Compare > &__bi1, _GuardedIterator< _RAIter, _Compare > &__bi2)

Detailed Description

template<typename _RAIter, typename _Compare>

class __gnu_parallel::_GuardedIterator< _RAIter, _Compare >" _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 _RAIter is not possible since _RAIter need not be a class.
