C++ 线程安全映射 [英] C++ Thread-Safe Map

问题描述

有谁知道我在哪里可以找到包装 std::map 并使其线程安全的实现?当我说线程安全时，我的意思是它只提供对地图的串行访问，一次一个线程.最佳情况下，此映射应仅使用标准库和/或 boost 结构.

Does anyone know where I can find an implimentation that wraps a std::map and makes it thread safe? When I say thread safe I mean that it offers only serial access to the map, one thread at a time. Optimally, this map should use only the standard-library and / or boost constructs.

推荐答案

不符合您指定的条件，但您可以查看 待定 容器.所谓的 concurrent_hash_map 允许多个线程同时访问映射中的数据.有一些细节，但一切都很好地记录在案，可以让您了解并发容器".根据您的需要，这可能完全不合适...

Does not meet the criteria that you have specified, but you could have a look at the TBB containers. There is so called concurrent_hash_map which allows multiple threads to access concurrently the data in the map. There are some details, but everything is nicely documented and can give you an idea of the "concurrent container". Depending on your needs this might be totally inappropriate...
