[Accumulators] Iterate through values in an accumulator_set
Hi all, I would like to know if it is possible to iterate through the values of an accumulator_set. I know how to fill the accumalator, extract results, but not how the get the values it contains. Best regards, Olivier

I'm not sure I understand. You want to iterate over the sampled data? The accumulator doesn't store it. E.g., if you are accumulating the sum, it just keeps track of the sum of the samples, not the samples themselves. -- Eric Niebler Boost Consulting www.boost-consulting.com

Yes. The accumulator doesn't store it. E.g., if you are accumulating the sum,
it just keeps track of the sum of the samples, not the samples themselves.
So, I still have to keep the samples in a std::vector. Then, a second question. I store the samples in a std::vector. What is the most efficient (time point of view) : use the std::vector of samples and std::for_each (as mentionned in the doc), or build the accumulator_set in conjunction with the std::vector ?
