8 | /// \brief Top container class for geometry transformations | |
9 | /// | |
10 | /// Geometry transformations can be filled in these ways: | |
11 | /// - by geometry builder when geometry is built via builders | |
12 | /// (this way is used when running simulation and building geometry | |
13 | /// via VirtualMC) | |
14 | /// - from Root geometry file (*.root) or ASCII file (*.dat) using | |
15 | /// the method LoadGeometryData(const TString& fileName) | |
16 | /// - from geometry loaded in AliGeomManager using | |
17 | /// the method LoadGeometryData() without arguments | |
18 | /// | |
