[ROOT] questions about MakeSelector

Hi rooters,
I have a root Tree h1 filled with a class Event
(very similar to the example  in the root/tutorial directory)
containing simple variables (float  etot, int ncount) and
also a  TClonesArray* fHits  of a class Hit.
To analyze the Trees in different files,
I made a TChain and used the MakeSelector method.
In the resulting h1analysis.h class I read

class h1analysis:public TSelector
{
    public:
//Event *fEvent;
Int_t       ncount;
Float_t    etot;
etc...
...
...
}

I wonder:
why the line Event* is commented?
why the class Hit and the TClonesArray are not mentioned  in h1analysis
class?
How can I read in the method Process of h1analysis class   the content
of the TClonesArray ?
Thanks
            Paolo
