bool operator< (const _GuardedIterator< _RAIter, _Compare > &__bi1, const _GuardedIterator< _RAIter, _Compare > &__bi2)
Compare two elements referenced by guarded iterators. bool operator<= (const _GuardedIterator< _RAIter, _Compare > &__bi1, const _GuardedIterator< _RAIter, _Compare > &__bi2)
Compare two elements referenced by guarded iterators.
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.
Constructor & Destructor Documentation
template<typename _RAIter , typename _Compare > __gnu_parallel::_GuardedIterator< _RAIter, _Compare >::_GuardedIterator (_RAIter __begin, _RAIter __end, _Compare & __comp) [inline]
