class RooCFunction2Ref<double,double,int>: public TObject

RooCFunction2Binding is a templated implementation of class RooAbsReal that binds generic C(++) functions to a RooAbsReal argument thus allowing generic C++ functions to be used as RooFit functions. Instances of function binding classes are fully functional RooFit function objects with one exception: if the bound function is _not_ a standard TMath or MathMore function the class cannot be persisted in a RooWorkspace without registering the function pointer first using RooCFunction2Binding::register().

This class is also known as (typedefs to this class)

Function documentation

void RooCFunction2Ref<VO,VI1,VI2> Streamer(TBuffer& R__b)

 Custom streamer for function pointer reference object. When writing,
 the function pointer is substituted by its registerd name. When function
 is unregistered name 'UNKNOWN' is written and a warning is issues. When
 reading back, the embedded name is converted back to a function pointer
 using the mapping service. When name UNKNOWN is encountered a warning is
 issues and a dummy null function is substituted. When the registered function
 name can not be mapped to a function pointer an ERROR is issued and a pointer
 to the dummy null function is substituted

VO operator()(double x, int y) const

 Evaluate embedded function

const char* name() const

 Return registered name of embedded function. If function
 is not registered return string with hex presentation
 of function pointer value

const char* argName(Int_t iarg)

 Return suggested name for i-th argument

return fmap()

VO dummyFunction(double , int )

 Dummy function used when registered function was not
 found in un-persisting object
