18 // Class AliMUONSlatGeometryBuilder
19 // -------------------------------
20 // Abstract base class for geometry construction per chamber.
25 // This Builder is designed according to the enveloppe methode. The basic idea is to be able to allow moves
26 // of the slats on the support panels.
27 // Those moves can be described with a simple set of parameters. The next step should be now to describe all
28 // the slats and their places by a unique
29 // class, which would make the SlatBuilder far more compact since now only three parameters can define a slat
30 // and its position, like:
31 // * Bool_t rounded_shape_slat
32 // * Float_t slat_length
33 // * Float_t slat_number or Float_t slat_position
