Classes
struct	BinnedLOutput
class	HijackMessageStream
	Hijacks all messages with given level and topic (and optionally object name) while alive. More...
class	LocalChangeMsgLevel
	Switches the message service to a different level while the instance is alive. More...
struct	WrapIntoTObject
	Wrap an object into a TObject. Sometimes needed to avoid reinterpret_cast or enable RTTI. More...

Function Documentation

checkIfRangesOverlap()

bool RooHelpers::checkIfRangesOverlap	(	RooArgSet const &	observables,
		std::vector< std::string > const &	rangeNames
	)

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.

std::unique_ptr< T > RooHelpers::cloneTreeWithSameParameters	(	T const &	arg,
		RooArgSet const *	observables = nullptr
	)

Clone RooAbsArg object and reattach to original parameters.
