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.

Clone method.

void TMethod::CreateSignature ( )

privatevirtual

Using the CINT method arg information create a complete signature string.

Reimplemented from TFunction.

Definition at line 114 of file TMethod.cxx.

TDataMember * TMethod::FindDataMember ( )

virtual

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)
