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 | // // | |
