19 | BuildGeometry of AliMUON for trigger chambers delegated to AliMUONSegmentationTriggerX (same strategy as for tracking chambers) | |
20 | ||
5fd73042 | 21 | Revision 1.5 2000/10/02 16:58:29 egangler |
22 | Cleaning of the code : | |
23 | -> coding conventions | |
24 | -> void Streamers | |
25 | -> some useless includes removed or replaced by "class" statement | |

28 | AliMUONSegmentation class has been made independent of AliMUONChamber. This makes | |
29 | it usable with any other geometry class. The link to the object to which it belongs is | |
30 | established via an index. This assumes that there exists a global geometry manager | |
31 | from which the pointer to the parent object can be obtained (in our case gAlice). | |
