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.

Definition at line 51 of file RooRealBinding.cxx.

◆ RooRealBinding() [2/2]

RooRealBinding::RooRealBinding ( const RooRealBinding other,
const RooArgSet nset = 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.
