8// AliITSUGeomTGeo is a simple interface class to TGeoManager //
9// It is used in the simulation and reconstruction in order to //
10// query the TGeo ITS geometry //
11// //
12// author - cvetan.cheshkov@cern.ch //
13// 15/02/2007 //
14// adapted to ITSupg 18/07/2012 - ruben.shahoyan@cern.ch //
15// RS: in order to preserve the static character of the class but //
16// make it dynamically access geometry, we need to check in every //
17// method if the structures are initialized. To be converted to //
18// singleton at later stage. //
19// //
20// Note on the upgrade detector types: //
21// The coarse type defines detectors served by different classes, //
75875328 22// like Pix. Each such a detector type can have kMaxSegmPerDetType //
451f5018 23// segmentations (pitch etc.) whose parameteres are stored in the //
75875328 24// AliITSsegmentation derived class (like AliITSUSegmentationPix) //
451f5018 25// This allows to have in the setup modules served by the same //
26// classes but with different segmentations. //
27// The full detector type is composed as: //
28// CoarseType*kMaxSegmPerDetType + segmentationType //
29// The only requirement on the segmentationType that should be //
30// < kMaxSegmPerDetType. //
31// The methods like GetLayerDetTypeID return the full detector type //
32// //
