### Data Members

        private:

              TDataMember* fDataMember  pointer to data member descriptor
                     Int_t fThisOffset  offset with the THIS object pointer
                   TString fName        Concatenated names of this realdata
          TMemberStreamer* fStreamer    Object to stream the data member.
                    Bool_t fIsObject    true if member is an object

## Class Description

      The TRealData class manages the effective list of all data members
      for a given class. For example for an object of class TLine that inherits
      from TObject and TAttLine, the TRealData object for a line contains the
      complete list of all data members of the 3 classes.

      The list of TRealData members in TClass is built when functions like
      object.Inspect or object.DrawClass are called.
