19 | Cleaning of the code : | |
20 | -> coding conventions | |
21 | -> void Streamers | |
22 | -> some useless includes removed or replaced by "class" statement | |

ecfa008b | 24 | Revision 1.5 2000/07/03 11:54:57 morsch |
25 | AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER | |
26 | The methods GetPadIxy and GetPadXxy of AliMUONSegmentation have changed name to GetPadI and GetPadC. | |

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