8/// \brief Top container class for geometry transformations
9///
a7d4e65b 10/// Geometry transformations can be filled in these ways:
11/// - by geometry builder when geometry is built via builders
327d1302 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
