Sometimes we need to use STL data structures such as map, unordered_map or set using a data type that doesn't have a hash or a comparator. Instead of coding things properly I will show an easy way to achieve the same thing with minimal effort. The idea is to use pointer casting. Let...
在C++中,<hash_map> 已经被弃用,建议使用 <unordered_map> 替代。 在C++11及之后的版本中,<hash_map> 已经被标记为弃用,并且未来可能会被完全移除。这是因为 <unordered_map> 提供了类似的功能,并且更加符合C++标准库的设计哲学。 为什么弃用 <hash_map>? 非标准:<...
–In unordered map hashing, STL performance is 60 to 70% faster than the current CLANG Win64, and 40 to 70% faster than the current CLANG Win32 in C++ Builder Comes with a new Visual Assist in the IDE –Fast code completion –Navigation and refactoring –and more Debugging will use PDB...
This caused me think about which situations I should use an unordered_map instead of a regular map (ordered map). Is an unordered_map always inherently faster than a map? in which cases should I use it? I'm asking here because I couldn't get a satisfactory answer after searching the we...

std::unordered_mapcrash more often than unsafe multithreaded use of astd::map? A customer had some code that used astd::map, and they found that when they switched tostd::unordered_mapit began to crash a lot more than it did before. Eventually, they traced the problem back to unsafe mul...
Being a probabilistic data structure, Redis Bloom filters do, indeed, sacrifice some accuracy, but in return, they get a very low memory footprint and response time. TIP You might ask why not use a Redis Set to answer some of the questions above. Redis Sets are used to store unordered ...
