ROOT::THistBufferedFill< HIST, SIZE > Class Template Reference

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

Buffers calls to Fill().

Once the buffer is full, on destruction of when calling Flush(), it sends the buffers off as an ideally vectorizable FillN() operation. It also serves as a multi-threaded way of filling the same histogram, reducing the locking frequency.

The HIST template can be either a THist instance, a THistImpl instance, or a THistLockedFill instance.
