Classes
class	ChangeOperModeRAII
	Struct to temporarily change the operation mode of a RooAbsArg until it goes out of scope. More...
struct	DisableCachingRAII
	Disable all caches for sub-branches in an expression tree. More...
class	HijackMessageStream

	Check if the parameters have a range, and warn if the range extends below / above the set limits.
std::string	getColonSeparatedNameString (RooArgSet const &argSet)
	Create a string with all sorted names of RooArgSet elements separated by colons.
std::pair< double, double >	getRangeOrBinningInterval (RooAbsArg const *arg, const char *rangeName)

Function Documentation

checkIfRangesOverlap()

bool RooHelpers::checkIfRangesOverlap	(	RooAbsPdf const &	pdf,
		RooAbsData const &	data,
		std::vector< std::string > const &	rangeNames,
		bool	splitRange
	)

Check if there is any overlap when a list of ranges is applied to a set of observables.

Parameters

[in]	pdf	the PDF
[in]	data	RooAbsCollection with the observables to check for overlap.
[in]	rangeNames	The names of the ranges.
[in]	splitRange	If true, each component of a RooSimultaneous will be checked individually for overlaps, with the range names in that component suffixed by _<cat_label>. See the SplitRange() command argument of RooAbsPdf::fitTo()` to understand where this is used.

checkRangeOfParameters()

void RooHelpers::checkRangeOfParameters	(	const RooAbsReal *	callingClass,
		std::initializer_list< const RooAbsReal * >	pars,
		double	min,
		double	max,
		bool	limitsInAllowedRange,
		std::string const &	extraMessage
	)

Check if the parameters have a range, and warn if the range extends below / above the set limits.

Parameters

[in]	callingClass	Class that's calling. Needed to include name and type name of the class in error message.
[in]	pars	List of all parameters to be checked.
[in]	min	Minimum of allowed range. min itself counts as disallowed.
[in]	max	Maximum of allowed range. max itself counts as disallowed.
[in]	limitsInAllowedRange	If true, the limits passed as parameters are part of the allowed range.
[in]	extraMessage	Message that should be appended to the warning.

getColonSeparatedNameString()

std::string RooHelpers::getColonSeparatedNameString

(

RooArgSet const &

argSet

)

Create a string with all sorted names of RooArgSet elements separated by colons.

Parameters

[in]

arg

argSet The input RooArgSet.

Definition at line 282 of file RooHelpers.cxx.

getRangeOrBinningInterval()

std::pair< double, double > RooHelpers::getRangeOrBinningInterval	(	RooAbsArg const *	arg,
		const char *	rangeName
	)

Get the lower and upper bound of parameter range if arg can be casted to RooAbsRealLValue.

If no range with rangeName is defined for the argument, this will check if a binning of the same name exists and return the interval covered by the binning. Returns {-infinity, infinity} if agument can't be casted to RooAbsRealLValue* or if no range or binning with the requested name exists.

Parameters

[in]	arg	RooAbsArg for which to get the range.
[in]	rangeName	The name of the range.

selectFromArgSet()

RooArgSet RooHelpers::selectFromArgSet	(	RooArgSet const &	argSet,
		std::string const &	names
	)

Construct a RooArgSet of objects in a RooArgSet whose names match to those in the names string.

Parameters

[in]	arg	argSet The input RooArgSet.
[in]	arg	names The names of the objects to select in a colon-separated string.
