Is there any equivalent std::algorithm similar to std::map::lower_bound for std::tr1::unordered_map ?
I have C++03 code that looks like this: #include <boost/tr1/unordered_map.hpp> ... std::tr1::unordered_map<std::string, int> mystuff; ... I started to wonder that i would suffer later...
I'm unable to use the insert function for a std::tr1::unordered_map, I keep receiving the following error when attempting to build: /usr/include/c++/4.2.1/tr1/hashtable:855:14: error: cannot initi...
How can I get a lower_bound in a slice of a std::map between two iterators (similar to std::lower_bound) with logarithmic complexity (similar to std::map::lower_bound) ?
Has anyone experienced with both GHashTable and std::tr1::unordered_map? I want to know which one to use and which one is more recommended. I couldn't find anything really useful online. Thanks,
I'd like to have an unordered_map which contains the occurrences of each key; the problem is that, when I print myMap, it's ordered instead. I know it'd be better to use C++11, but I cannot for some
std::map has an insert method that takes a "hint" iterator that will reduce the insertion time from log(n) to constant time if the hint is correct. Its pretty obvious how this would work, since the
I've been investigating some strange behavior regarding the boost serialization of a std::tr1::unordered_map with a custom key. Between serializing a key and serializing the unordered_map that cont...
We are working on a game project for school in c++. I'm in charge of the map object, who will contain Entities like bombs, players, walls and boxes. I have 3 containers in my map: A std::list for
Is there any way to move unordered_map values to a vector? All the ways I was able to find copy values (like in my example) instead of using something similar to std::move. I would like to not copy
