It does somewhat. I was thinking something like this must be necessary, but I am still confused about the following: In the b.IsReading() block of TCollection's Streamer (which I will need to mirror), one loops over the number of objects to input and there is code like: TObject* obj; //... loop { b >> obj; } If I write a RegistryItemXxx<T>:RegistryItem:TObject object in the ``IsWriting'' block, how will ROOT know to give me this full object back, when all I call is TObject's operator>>(). I know that rootcint will generate an operator>>(TBuffer&,Class*&) for the Class it is run on. Is this somehow called durring ``b >> obj;''? Maybe this magic (using A.C. Clark's definition) is something fundamental (seperate from the complication of templates) about ROOT's I/O that I don't understand. Thanks, -Brett.
