//  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.
