Erase without invalidating iterator sex dating in iconium iowa

It then loops on all of them calculating a derived value for each. Erasing an element from a multimap also does not invalidate any iterators, except, of course, for iterators that actually point to the element that is being erased." I prefer not to suppose that, because if I change the container, I must change my code too, but you can assume iterators are not invalidated after an insert if you prefer.You did not find that statement because it it is false.I'm not familiar to multimap, but I suppose that depending on the position of the new element inserted, you could access it too, and calculate a new item from that item calculated previously.I suppose what you want to do is iterate through the original elements of the container, not through the original and the new elements, but only you know what you want to do.Or in other words, we don’t guarantee that it will work. Basically, an iterator doesn’t synchronize its operations with any concurrent operation.

It then loops on all of them calculating a derived value for each. The standard says about associative containers [23.1.2/8]: The insert members shall not affect the validity of iterators and references to the container, and the erase members shall invalidate only iterators and references to the erased elements.

Ok so the iterator isn't invalid, but back to my pseudo code:- Data Item:: Multi Map::const_iterator iter = data Items.lower_bound(parameter Reference); Data Item:: Multi Map::const_iterator end = data Items.upper_bound(parameter Reference); while (iter != end) could you end up processing items more than once?
