40 // 03-12-02 V.Ivanchenko fix a bug in model selection
41 // 20-01-03 Migrade to cut per region (V.Ivanchenko)
42 // 27-01-03 Make models region aware (V.Ivanchenko)
43 // 13-02-03 The set of models is defined for region (V.Ivanchenko)
44 // 26-03-03 Add GetDEDXDispersion (V.Ivanchenko)
45 // 13-04-03 Add startFromNull (V.Ivanchenko)
46 // 13-05-03 Add calculation of precise range (V.Ivanchenko)
47 // 21-07-03 Add UpdateEmModel method (V.Ivanchenko)
48 // 03-11-03 Substitute STL vector for G4RegionModels (V.Ivanchenko)
49 // 11-04-05 Remove access to fluctuation models (V.Ivanchenko)
50 // 10-01-06 PreciseRange -> CSDARange (V.Ivantchenko)
51 // 20-01-06 Introduce G4EmTableType and reducing number of methods (VI)
52 // 13-05-06 Add GetModel by index method (VI)
53 // 15-03-07 Add maxCutInRange (V.Ivanchenko)
54 // 08-04-08 Simplify Select method for only one G4RegionModel (VI)
55 // 03-08-09 Removed unused members and simplify model search if only one
56 // model is used (VI)
57 // 14-07-11 Use pointer to the vector of cuts and not local copy (VI)
58 //
59 // Class Description:
60 //
61 // It is the unified energy loss process it calculates the continuous
62 // energy loss for charged particles using a set of Energy Loss
63 // models valid for different energy regions. There are a possibility
64 // to create and access to dE/dx and range tables, or to calculate
65 // that information on fly.
