C ++线程安全地图 [英] C++ Thread-Safe Map

问题描述

有没有人知道我在哪里可以找到一个包装一个STL地图并使其线程安全的实现？当我说线程安全我的意思是它提供只有串行访问地图，一次一个线程。最佳地，此地图应只使用STL和或boost构造。

Does anyone know where I can find an implimentation that wraps an STL 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 STL and or boost constructs.

推荐答案

不符合您指定的条件，可以查看 TBB 容器。有一种叫做 concurrent_hash_map 的方法，它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，可以给你一个并发容器的想法。根据你的需要，这可能是完全不合适的...

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...
