3 | // Base class for ALICE modules. Both sensitive modules (Modules) and // | |
4 | // non-sensitive ones are described by this base class. This class // | |
5 | // supports the hit and digit trees produced by the simulation and also // | |
6 | // the objects produced by the reconstruction. // | |
7 | // // | |
8 | // This class is also responsible for building the geometry of the // | |
9 | // Modules. // | |
