自定义的分配器快速的std :: wstring的分配 [英] Custom allocator for fast std::wstring allocations

问题描述

有没有可以用的std :: wstring的被用来实施的快速的分配格局就像任何开源分配器（可能在升压）在这个博客帖子 <？ / p>

Boost.Pool <一个href=\"http://stackoverflow.com/questions/10451585/using-vectorwstring-with-boost-pool-allocator\">doesn't似乎非常适合这一目的。

解决方案

没有，没有（我搜索了几个小时，一次）。如果你不小心使用过程中释放内存，它是相当简单的做自己。如果要动态地释放它，那么它就变成对自由列表管理，LRU等大量的工作。

Is there any open-source allocator (possibly in Boost) that can be used with std::wstring implementing a fast allocation pattern like the one showed in this blog post?

Boost.Pool doesn't seem well suited for this purpose.

解决方案

No, there isn't (I searched for a couple of hours, once). If you don't care to release memory during usage, it is fairly simple to do yourself. If you want to release it dynamically, then it becomes a lot of work regarding free list management, LRU, etc.
