19 @brief Implementation of AliFMD base class
21 //____________________________________________________________________
23 // Forward Multiplicity Detector based on Silicon wafers. This class
24 // is the driver for especially simulation.
26 // The Forward Multiplicity Detector consists of 3 sub-detectors FMD1,
27 // FMD2, and FMD3, each of which has 1 or 2 rings of silicon sensors.
29 // This is the base class for all FMD manager classes.
31 // The actual code is done by various separate classes. Below is
32 // diagram showing the relationship between the various FMD classes
33 // that handles the simulation

53 // This defines the interface for the various parts of AliROOT that
54 // uses the FMD, like AliFMDSimulator, AliFMDDigitizer,
55 // AliFMDReconstructor, and so on.
58 // This is a concrete implementation of the AliFMD interface.

63 // This is a concrete implementation of the AliFMD interface.
64 // It is the responsibility of this class to create the FMD
65 // geometry, process hits in the FMD, and serve hits and digits to
66 // the various clients.
69 // This is the base class for the FMD simulation tasks. The
70 // simulator tasks are responsible to implment the geoemtry, and
