RooAbsNumGenerator() [2/2]

RooAbsNumGenerator::RooAbsNumGenerator	(	const RooAbsReal &	func,
		const RooArgSet &	genVars,
		bool	verbose = false,
		const RooAbsReal *	maxFuncVal = nullptr
	)

Initialize an accept-reject generator for the specified distribution function, which must be non-negative but does not need to be normalized over the variables to be generated, genVars.

The function and its dependents are cloned and so will not be disturbed during the generation process.
