5fd73042 | 18 | Revision 1.7 2000/10/03 21:48:07 morsch |
19 | Adopt to const declaration of some of the methods in AliSegmentation. | |
20 | ||
c3eff6ad | 21 | Revision 1.6 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 | |
26 | ||
ecfa008b | 27 | Revision 1.5 2000/07/03 11:54:57 morsch |
28 | AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER | |
29 | The methods GetPadIxy and GetPadXxy of AliMUONSegmentation have changed name to GetPadI and GetPadC. | |
30 | ||

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