2 // *** Class AliRsnCutValue ***
4 // This cut implementation can be used to cut generically on
5 // any value which can be computed from AliRsnValue class.
6 // Since that value is implemented always as a Double_t one,
7 // then this cut operates only with the Double_t data members
8 // of the AliRsnCut base class.
9 // It allows to cusomize the reference AliRsnValue object by
10 // means of a getter that returns a pointer to it.
11 // This cut can apply to any kind of object, but the type of
12 // target must be one of those for which the chosen value type
13 // makes sense to be computed
