Member Function Documentation

fill() [1/2]

virtual unsigned Monitored::HistogramFiller::fill ( const VariablesPack &  ) const

pure virtual

Method that actually fills the ROOT object.

Returns

number of fills performed

Implemented in Monitored::HistogramFillerTree, Monitored::HistogramFiller1D, Monitored::HistogramFiller2DGeneric< H >, Monitored::HistogramFiller2DProfile, Monitored::HistogramFillerEfficiency, Monitored::CumulativeHistogramFiller1D, and Monitored::VecHistogramFiller1D.

fill() [2/2]

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

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

inlineprotected

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
