2 | // Class AliRsnCutPIDTPC | |
3 | // | |
4 | // General implementation of a single cut strategy, which can be: | |
5 | // - a value contained in a given interval [--> IsBetween() ] | |
6 | // - a value equal to a given reference [--> MatchesValue()] | |
7 | // | |
8 | // In all cases, the reference value(s) is (are) given as data members | |
9 | // and each kind of cut requires a given value type (Int, UInt, Double), | |
10 | // but the cut check procedure is then automatized and chosen thanks to | |
11 | // an enumeration of the implemented cut types. | |
12 | // At the end, the user (or any other point which uses this object) has | |
13 | // to use the method IsSelected() to check if this cut has been passed. | |
