14  \ingroup Roofit
15 
16 RooCFunction4Binding is a templated implementation of class RooAbsReal that binds
17 generic C(++) functions to a RooAbsReal argument thus allowing generic C++
18 functions to be used as RooFit functions. Instances of function binding
19 classes are fully functional RooFit function objects with one exception:
20 if the bound function is _not_ a standard TMath or MathMore function the
21 class cannot be persisted in a RooWorkspace without registering the function
22 pointer first using RooCFunction4Binding<T1,T2,T3,T4>::register().
