-// Class AliRsnCut
+// *** Class AliRsnCut ***
//
-// General implementation of a single cut strategy, which can be:
-// - a value contained in a given interval [--> IsBetween() ]
-// - a value equal to a given reference [--> MatchesValue()]
+// Cut base class: all other cuts inherit from it.
+// The 'core' of the class is the method "IsSelected()" which
+// must be overloaded by any specific cut implementation.
//
-// In all cases, the reference value(s) is (are) given as data members
-// and each kind of cut requires a given value type (Int, UInt, Double),
-// but the cut check procedure is then automatized and chosen thanks to
-// an enumeration of the implemented cut types.
-// At the end, the user (or any other point which uses this object) has
-// to use the method IsSelected() to check if this cut has been passed.
+// This class provides some default instruments to check values
+// agains a reference or an allowed range, in order to permit
+// a unique way to execute such kind of checks.
