ROOT::Experimental::RHistConcurrentFillManager< HIST, SIZE > Class Template Reference

template<class HIST, int SIZE = 1024>
class ROOT::Experimental::RHistConcurrentFillManager< HIST, SIZE >

Manages the synchronization of calls to FillN().

The HIST template can be a RHist instance. This class hands out RHistConcurrentFiller objects that can concurrently fill the histogram. They buffer calls to Fill() until the buffer is full, and then swap the buffer with that of the RHistConcurrentFillManager. The manager than fills the histogram.
