bool operator (guarded_iterator< RandomAccessIterator, Comparator > &bi1, guarded_iterator< RandomAccessIterator, Comparator > &bi2)

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.
