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.

Constructor & Destructor Documentation

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.
