◆ THistBinStat()

template<class DATA , class... BASES>
 ROOT::Experimental::Detail::THistBinStat< DATA, BASES >::THistBinStat ( DATA & data, int index )
inline

Definition at line 370 of file THistData.hxx.

◆ GetUncertainty() [1/2]

template<class DATA , class... BASES>
template<bool B = true, class = typename std::enable_if<B && HasBinUncertainty()>::type>
 double ROOT::Experimental::Detail::THistBinStat< DATA, BASES >::GetUncertainty ( ) const
inline

Calculate the bin content's uncertainty for the given bin, using base class information, i.e.

forwarding to a base's GetUncertaintyImpl().

Definition at line 383 of file THistData.hxx.

◆ GetUncertainty() [2/2]

template<class DATA , class... BASES>
template<bool B = true, class = typename std::enable_if<B && !HasBinUncertainty()>::type>
 double ROOT::Experimental::Detail::THistBinStat< DATA, BASES >::GetUncertainty ( ... ) const
inline

Calculate the bin content's uncertainty for the given bin, using Poisson statistics on the absolute bin content.

Only available if no base provides this functionality. Requires GetContent().

Definition at line 391 of file THistData.hxx.

◆ HasBinUncertainty()

template<class DATA , class... BASES>
 static constexpr bool ROOT::Experimental::Detail::THistBinStat< DATA, BASES >::HasBinUncertainty ( )
inlinestatic

Whether this provides storage for uncertainties, or whether uncertainties are determined as poisson uncertainty of the content.

Definition at line 374 of file THistData.hxx.

◆ HaveUncertainty() [1/2]

template<class DATA , class... BASES>
template<class T >
 static auto ROOT::Experimental::Detail::THistBinStat< DATA, BASES >::HaveUncertainty ( const T * This ) -> decltype(This->GetUncertaintyImpl())
staticprivate

Check whether double T::GetBinUncertaintyImpl(int) can be called.

◆ HaveUncertainty() [2/2]

template<class DATA , class... BASES>
template<class T >
 static char ROOT::Experimental::Detail::THistBinStat< DATA, BASES >::HaveUncertainty ( ... )
staticprivate

Fall-back case for check whether double T::GetBinUncertaintyImpl(int) can be called.
