提高::蓄电池：这对于运营商sample_type？ [英] boost::accumulator: which operators for sample_type?

问题描述

我想用一个boost ::累加器定义我的自定义类的移动平均线：

I want to use a boost::accumulator for defining a moving average of my custom class:

boost::accumulators::accumulator_set<MySample, boost::accumulators::stats<boost::accumulators::tag::rolling_mean> >

我的问题是我的样本是用户定义的类（vector实现另一个库）。

My problem is that my sample is a user defined class (vector implementation of another library).

我见过的<一个href=\"http://stackoverflow.com/questions/4316716/is-it-possible-to-use-boost-accumulators-with-vectors\">in这个帖子这是可以定义的std ::向量蓄能器，但它并没有指定运营商必须重载，因为它与升压/累加器/数字/功能/ vector.hpp重载它们。

I've seen in this post that's possible to define accumulators for std::vectors, but it does not specify which operator must be overloaded because it overloads them with boost/accumulators/numeric/functional/vector.hpp.

如果我想使用蓄能器与用户自定义的样品类，经营者，我必须超载又如何？

If I want to use accumulator with an user-defined sample class, which operator I must overload and how?

推荐答案

答案会根据您所使用的统计信息不同，不幸的是这一切都不是有据可查的。最好的答案我可以给是尝试编译它，看看错误信息，添加所需的操作人员，冲洗，重复，直到工作的事情。 ： - /

The answer is going to differ depending on the stats you use, and sadly none of this is well documented. The best answer I can give is to try to compile it, look at the error message, add the needed operator, rinse, repeat until things work. :-/
