class TMethod: public TFunction

Each ROOT class (see TClass) has a linked list of methods.
This class describes one single method (member function).
The method info is obtained via the CINT api. See class TCling.

The method information is used a.o. by the THml class and by the
TTree class.

Function documentation

TMethod(MethodInfo_t* info = 0, TClass* cl = 0)
 Default TMethod ctor. TMethods are constructed in TClass.
 Comment strings are pre-parsed to find out whether the method is
 a context-menu item.
TMethod(const TMethod& org)
 Copy ctor.
TMethod& operator=(const TMethod& rhs)
 Assignment operator.
TObject * Clone(const char* newname = "") const
 Clone method.
const char * GetCommentString()
 Returns a comment string from the class declaration.
void CreateSignature()
 Using the CINT method arg information create a complete signature string.
TDataMember * FindDataMember()
 Tries to guess DataMember from comment string
 and Method's name <==(only if 1 Argument!).
 If more then one argument=> returns pointer to the last argument.
 It also sets MethodArgs' pointers to point to specified data members.

 The form of comment string defining arguments is:
 void XXX(Int_t x1, Float_t y2) //*ARGS={x1=>fX1,y2=>fY2}
 where fX1, fY2 are data fields in the same class.
 ("pointers" to data members)
TMethodCall * GetterMethod()
 Return call environment for the getter method in case this is a
 *TOGGLE method (for the context menu).
Bool_t IsValid()
 Return true if this function object is pointing to a currently
 loaded function.  If a function is unloaded after the TMethod
 is created, the TMethod will be set to be invalid.
TMethodCall * SetterMethod()
 Return call environment for this method in case this is a
 *TOGGLE method which takes a single boolean or integer argument.
TList * GetListOfMethodArgs()
 Returns methodarg list and additionally updates fDataMember in TMethod by
 calling FindDataMember();
void SetMenuItem(const char* docstring)
 Set the menu item as prescribed in the doctstring.
Bool_t Update(MethodInfo_t* info)
 Update the TMethod to reflect the new info.

 This can be used to implement unloading (info == 0) and then reloading
 (info being the 'new' decl address).
void SetMenuItem(const char* docstring)
TClass * GetClass() const
{ return fClass; }
EMenuItemKind IsMenuItem() const
{ return fMenuItem; }
const char * Getter() const
{ return fGetter; }
