Constructor & Destructor Documentation

◆ RooRealBinding() [1/2]

RooRealBinding::RooRealBinding	(	const RooAbsReal &	func,
		const RooArgSet &	vars,
		const RooArgSet *	nset = `nullptr`,
		bool	clipInvalid = `false`,
		const TNamed *	rangeName = `nullptr`
	)

Construct a lightweight function binding of RooAbsReal func to variables 'vars'.

Use the provided nset as normalization set to be passed to RooAbsReal::getVal() If rangeName is not null, use the range of with that name as range associated with the variables of this function binding. If clipInvalid is true, values requested to the function binding that are outside the defined range of the variables are clipped to fit in the defined range.
