fill() [2/2]

template<class H , typename W , typename C , typename ... Ms>

unsigned Monitored::HistogramFiller::fill ( W  weight, C  cut, const Ms &...  m  ) const

Fill histogram from IMonitoredVariable.

Supports arbitrary dimensions and double/string representation.

Template Parameters

H	histogram type (TH1, TH2, ...)

Parameters

weight	weight accessor (use detail::noWeight if not needed)
cut	cut mask accessor (use detail::noCut if not needed)
m...	IMonitoredVariable list to fill from
