RooRealVar Class Reference

RooRealVar represents a variable that can be changed from the outside.

For example by the user or a fitter.

It can be written into datasets, can hold a (possibly asymmetric) error, and can have several ranges. These can be accessed with names, to e.g. limit fits or integrals to sub ranges. The range without any name is used as default range.

void RooRealVar::setMax	(	const char *	name,
		double	value
	)

Set maximum of name range to given value.

If name is null maximum of default range is set

setMin() [1/2]

void RooRealVar::setMin	(	const char *	name,
		double	value
	)

Set minimum of name range to given value.

If name is null minimum of default range is set

setRange() [1/4]

void RooRealVar::setRange	(	const char *	name,
		double	min,
		double	max
	)

Set a fit or plotting range.

Ranges can be selected for e.g. fitting, plotting or integration. Note that multiple variables can have ranges with the same name, so multi-dimensional PDFs can be sliced. See also the tutorial rf203_ranges.C

Parameters

[in]	name	Name this range (so it can be selected later for fitting or plotting). If the name is nullptr, the function sets the limits of the default range.
[in]	min	Miniminum of the range.
[in]	max	Maximum of the range.

setRange() [2/4]

void RooRealVar::setRange	(	const char *	name,
		RooAbsReal &	min,
		RooAbsReal &	max
	)

Set or modify a parameterised range, i.e., a range the varies in dependence of parameters.

See setRange() for more details.

setRange() [3/4]

void RooRealVar::setRange ( double  min, double  max  )

inline

Set the limits of the default range.

Definition at line 80 of file RooRealVar.h.

setRange() [4/4]

void RooRealVar::setRange ( RooAbsReal &  min, RooAbsReal &  max  )

inline

Set parameterised limits of the default range. See setRange(const char*, RooAbsReal&, RooAbsReal&).

setVal() [1/2]

void RooRealVar::setVal ( double  value )

overridevirtual

Set value of variable to 'value'.

If 'value' is outside range of object, clip value into range

Implements RooAbsRealLValue.

Definition at line 242 of file RooRealVar.cxx.

setVal() [2/2]

void RooRealVar::setVal ( double  value, const char *  rangeName  )

overridevirtual

Set value of variable to value.

If value is outside of the range named rangeName, clip value into that range.

sharedProp()

std::shared_ptr< RooRealVarSharedProperties > RooRealVar::sharedProp ( ) const

protected

Hand out our shared property, create on the fly and register in shared map if necessary.

Definition at line 1270 of file RooRealVar.cxx.

sharedPropList()

RooRealVar::SharedPropertiesMap * RooRealVar::sharedPropList ( )

staticprotected

List of properties shared among clones of a variable.

Return a reference to a map of weak pointers to RooRealVarSharedProperties.

Streamer()

void RooRealVar::Streamer ( TBuffer &  R__b )

overridevirtual

Stream an object of class RooRealVar.

translate()

void RooRealVar::translate ( RooFit::Detail::CodeSquashContext &  ctx ) const

overridevirtual

This function defines a translation for each RooAbsReal based object that can be used to express the class as simple C++ code.

The function adds the code represented by each class as an std::string (that is later concatenated with code strings from translate calls) to form the C++ code that AD tools can understand. Any class that wants to support AD, has to implement this function.

Parameters

[in]

ctx

An object to manage auxiliary information for code-squashing. Also takes the code string that this class outputs into the squashed code through the 'addToCodeBody' function.

Reimplemented from RooAbsArg.

Definition at line 85 of file RooRealVar.cxx.

valueResetCounter()

std::size_t RooRealVar::valueResetCounter ( ) const

inline

Returns how many times the value of this RooRealVar was reset.

Definition at line 55 of file RooRealVar.h.

writeToStream()

void RooRealVar::writeToStream ( std::ostream &  os, bool  compact  ) const

overridevirtual

Write object contents to given stream.

Reimplemented from RooAbsRealLValue.
