## Class Description

      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 TCint.

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

TMethod(G__MethodInfo *info, TClass *cl) : TFunction(info)

     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& orig) : TFunction(orig)

     Copy ctor.

~TMethod()

     Cleanup.

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).

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();

### Inline Functions

                 TMethod& operator=(const TMethod& rhs)
                  TClass* GetClass() const
            EMenuItemKind IsMenuItem() const
              const char* Getter() const
                     void SetMenuItem(EMenuItemKind menuItem)
                  TClass* Class()
                  TClass* IsA() const
                     void ShowMembers(TMemberInspector& insp, char* parent)
                     void Streamer(TBuffer& b)
                     void StreamerNVirtual(TBuffer& b)
