Member Data Documentation

cut

const Monitored::IMonitoredVariable* Monitored::HistogramFiller::VariablesPack::cut = nullptr

pointer to cut mask variable, typically absent

Definition at line 113 of file HistogramFiller.h.

m_var

boost::container::small_vector<const Monitored::IMonitoredVariable*, 3> Monitored::HistogramFiller::VariablesPack::m_var

private

Vector with small buffer optimization to avoid dynamic allocation for the most common case of histograms with a maximum of 3 variables.

Only 3D TEfficiency and TTress need more.

Definition at line 118 of file HistogramFiller.h.

weight

const Monitored::IMonitoredVariable* Monitored::HistogramFiller::VariablesPack::weight = nullptr

pointer to weight variable, typically absent

Definition at line 112 of file HistogramFiller.h.
