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.
