ROOT::Experimental::RHistConcurrentFiller< BinContentType > Class Template Reference

template<typename BinContentType>
class ROOT::Experimental::RHistConcurrentFiller< BinContentType >

A histogram filler to concurrently fill an RHist.

auto hist = std::make_shared<ROOT::Experimental::RHist<int>>(10, std::make_pair(5, 15));
{
   ROOT::Experimental::RHistConcurrentFiller filler(hist);
   auto context = filler.CreateFillContext();
   context->Fill(8.5);
}
// hist->GetBinContent(ROOT::Experimental::RBinIndex(3)) will return 1

Warning

This is part of the ROOT 7 prototype! It will change without notice. It might trigger earthquakes. Feedback is welcome!
