Global functions class (global functions are obtaine from CINT).
This class describes one single global function.
The TROOT class contains a list of all currently defined global
functions (accessible via TROOT::GetListOfGlobalFunctions()).

Function documentation

TFunction(MethodInfo_t* info = 0)
 Default TFunction ctor. TFunctions are constructed in TROOT via
 a call to TCling::UpdateListOfGlobalFunctions().
TFunction(const TFunction& orig)
 Copy operator.
TFunction& operator=(const TFunction& rhs)
 Assignment operator.
 TFunction dtor deletes adopted CINT MethodInfo.
TObject * Clone(const char* newname = "") const
 Clone method.
void CreateSignature()
 Using the CINT method arg information to create a complete signature string.
const char * GetSignature()
 Return signature of function.
TList * GetListOfMethodArgs()
 Return list containing the TMethodArgs of a TFunction.
const char * GetReturnTypeName() const
 Get full type description of function return type, e,g.: "class TDirectory*".
std::string GetReturnTypeNormalizedName() const
 Get the normalized name of the return type.  A normalized name is fully
 qualified and has all typedef desugared except for the 'special' typedef
 which include Double32_t, Float16_t, [U]Long64_t and std::string.  It
 also has std:: removed [This is subject to change].

Int_t GetNargs() const
 Number of function arguments.
Int_t GetNargsOpt() const
 Number of function optional (default) arguments.
Long_t Property() const
 Get property description word. For meaning of bits see EProperty.
Long_t ExtraProperty() const
 Get property description word. For meaning of bits see EProperty.
TDictionary::DeclId_t GetDeclId() const
void * InterfaceMethod() const
 Return pointer to the interface method. Using this pointer we
 can find which TFunction belongs to a CINT MethodInfo object.
 Both need to have the same InterfaceMethod pointer.
Bool_t IsValid()
 Return true if this function object is pointing to a currently
 loaded function.  If a function is unloaded after the TFunction
 is created, the TFunction will be set to be invalid.
const char * GetMangledName() const
 Returns the mangled name as defined by CINT, or 0 in case of error.
const char * GetPrototype() const
 Returns the prototype of a function as defined by CINT, or 0 in
 case of error.
void ls(Option_t* option = "") const
 List TFunction name and title.
void Print(Option_t* option = "") const
 Print TFunction name and title.
Bool_t Update(MethodInfo_t* info)
 Update the TFunction to reflect the new info.

 This can be used to implement unloading (info == 0) and then reloading
 (info being the 'new' decl address).
