NAME

__gnu_parallel::_GuardedIterator< _RAIter, _Compare > - _Iterator wrapper supporting an implicit supremum at the end of the sequence, dominating all comparisons.

SYNOPSIS

Public Member Functions _GuardedIterator (_RAIter __begin, _RAIter __end, _Compare &__comp) Constructor. Sets iterator to beginning of sequence. operator _RAIter () Convert to wrapped iterator. std::iterator_traits< _RAIter >::value_type & operator* () Dereference operator. _GuardedIterator< _RAIter, _Compare > & operator++ () Pre-increment operator. Friends bool operator< (_GuardedIterator< _RAIter, _Compare > &__bi1, _GuardedIterator< _RAIter, _Compare > &__bi2) Compare two elements referenced by guarded iterators. bool operator<= (_GuardedIterator< _RAIter, _Compare > &__bi1, _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. Definition at line 73 of file multiway_merge.h.
