Class Description


                                                                      
 TSelectorScalar                                                      
                                                                      
 Named scalar type, based on Long64_t, streamable, storable and       
 mergable. Ideally to be used in tree selectors in the PROOF          
 environment due to its merge fucntionality which allows a single     
 merged value to be returned to the user.                             
                                                                      




void Inc(Long_t n)


 Increment scalar value by n.



Int_t Merge(TCollection *list)


 Merge scalars with scalars in the list. The scalar values are added.
 Returns the number of scalars that were in the list.



 TSelectorScalar(const char *name = "", Long64_t val = 0)




 ~TSelectorScalar()
