1. STL map: reverse iterator for lower_bound?    bytes.com

On 2008-04-03 23:07, qlin88@gmail.com wrote: Hi, > In STL multi-map, the lower_bound, upper_bound,equal_range all return an iterator. Now ifone wants to iterate from an upper bound towards a lower bound, what would be the best way to do it? > I tried to interate backwards with an iterator, but the begin() element was not properly included. You can use reverse_iterators and ...

2. Class design with tightly bound iterator    bytes.com

P: n/a Jim Langston I am working on a class design to contain the indices of triangle lists for body parts. This is for 3d modeling. As as start I have: class PartTriangles { public: PartTriangels( const std::string& Name ): Name( Name ) {} private: std::string Name; std::set

3. must iterator be bound to owner/source?    bytes.com

I have a deque-like container that I want to give segmented iterators. The implementation uses pool allocation where iterators use indices instead of pointers. The standard iterator type has a reference to the pool and an index. The local_iterator type, which is used within a pool range, just needs an index to operate. But this means that a local iterator from ...

4. What is the defined behavior of past bound iterator    bytes.com

I'm wondering is the standard defined behavior of past bound iterator. In the following example it seems that afer first "--it", it point to -1 index. I'm wondering if it is true independent of which STL implementation that I am using. #include #include int main(int argc, char *argv[]) { std::vector v; for(int i = 0; i < 10; ++ ...
