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

#include <multiway_merge.h>


_GuardedIterator (_RAIter __begin, _RAIter __end, _Compare &__comp)
Constructor. Sets iterator to beginning of sequence. operator _RAIter () const
Convert to wrapped iterator. std::iterator_traits< _RAIter >::value_type & operator* () const
Dereference operator. _GuardedIterator< _RAIter, _Compare > & operator++ ()
Pre-increment operator.


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.

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.

template<typename _RAIter , typename _Compare > __gnu_parallel::_GuardedIterator< _RAIter, _Compare >::_GuardedIterator (_RAIter __begin, _RAIter __end, _Compare & __comp) [inline]

Constructor. Sets iterator to beginning of sequence.

Parameters

__begin Begin iterator of sequence.
__end End iterator of sequence.
__comp Comparator provided for associated overloaded compare operators.
