14 \ingroup Roofit
15
16RooCFunction1Binding is a templated implementation of class RooAbsReal that binds
17generic C(++) functions to a RooAbsReal argument thus allowing generic C++
18functions to be used as RooFit functions. Instances of function binding
19classes are fully functional RooFit function objects with one exception:
20if the bound function is _not_ a standard TMath or MathMore function the
21class cannot be persisted in a RooWorkspace without registering the function
22pointer first using RooCFunction1Binding<T1,T2>::register().
