d6c3334d 19/// \class AliMUONVDigit
20///
21/// This is the base class of a MUON digit that most client code should deal with.
22/// There should be no reason to have to use a concrete class in most cases.
23///
24/// All digits have basic features, like :
25///
26/// - a way to identify it : detection element, electronics card and
27/// channel, cathode. Note that some static methods exists to compact
28/// those 4 informations into a single 4 bytes integer (stored in the
29/// fUniqueID data member present in all TObjects).
30///
31/// - its charge
32///
33/// - a set of boolean methods to indicate whether the digit has been calibrated, etc...
34///
35/// In addition, if HasMCInformation is true, the digit store also the list
36/// of MC tracks that contributed to its charge
37///
38/// Also, if HasGeometryInformation is true, the digit knows the position and
39/// the (half) dimensions (in cm) of the pad it corresponds to.
