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