Function Documentation

checkRangeOfParameters()

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

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.

tokenise()

std::vector< std::string > RooHelpers::tokenise	(	const std::string &	str,
		const std::string &	delims,
		bool	returnEmptyToken
	)

Tokenise the string by splitting at the characters in delims.

Consecutive delimiters are collapsed, so that no delimiters will appear in the tokenised strings, and no emtpy strings are returned.

Parameters

[in]	str	String to tokenise.
[in]	delims	One or more delimiters used to split the string.
[in]	returnEmptyToken	If the string is empty, return one empty token. Default is to return an empty vector.
