Member Function Documentation

◆ Fill() [1/3]

template<typename BinContentType >

template<typename... A>

void ROOT::Experimental::RHistFillContext< BinContentType >::Fill ( const A &... args )

inline

Fill an entry into the histogram.

For weighted filling, pass an RWeight as the last argument. This is not available for integral bin content types (see RHistEngine::SupportsWeightedFilling).

If one of the arguments is outside the corresponding axis and flow bins are disabled, the entry will be silently discarded.

Throws an exception if the number of arguments does not match the axis configuration, or if an argument cannot be converted for the axis type at run-time.

Parameters

[in] args the arguments for each axis

See also: RHist::Fill(const A &...args)

Definition at line 99 of file RHistFillContext.hxx.

◆ Fill() [2/3]

template<typename BinContentType >

template<typename... A>

void ROOT::Experimental::RHistFillContext< BinContentType >::Fill ( const std::tuple< A... > & args )

inline

Fill an entry into the histogram.

If one of the arguments is outside the corresponding axis and flow bins are disabled, the entry will be silently discarded.

Throws an exception if the number of arguments does not match the axis configuration, or if an argument cannot be converted for the axis type at run-time.

Parameters

[in] args the arguments for each axis

See also: RHist::Fill(const std::tuple<A...> &args)

Definition at line 59 of file RHistFillContext.hxx.

◆ Fill() [3/3]

template<typename BinContentType >

template<typename... A>

void ROOT::Experimental::RHistFillContext< BinContentType >::Fill	(	const std::tuple< A... > &	args,
		RWeight	weight )

inline

Fill an entry into the histogram with a weight.

This overload is not available for integral bin content types (see RHistEngine::SupportsWeightedFilling).

If one of the arguments is outside the corresponding axis and flow bins are disabled, the entry will be silently discarded.

Throws an exception if the number of arguments does not match the axis configuration, or if an argument cannot be converted for the axis type at run-time.
