18Introducing Riostream.h
19
70479d0e 20Revision 1.8 2001/03/20 13:32:37 egangler
21includes cleanup
22
b6ae9e79 23Revision 1.7 2000/10/02 16:58:29 egangler
24Cleaning of the code :
25-> coding conventions
26-> void Streamers
27-> some useless includes removed or replaced by "class" statement
28
ecfa008b 29Revision 1.6 2000/07/13 16:19:44 fca
30Mainly coding conventions + some small bug fixes
31
ef42d733 32Revision 1.5 2000/07/03 11:54:57 morsch
33AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER
34The methods GetPadIxy and GetPadXxy of AliMUONSegmentation have changed name to GetPadI and GetPadC.
35
a30a000f 36Revision 1.4 2000/06/28 15:16:35 morsch
37(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
38to allow development of slat-muon chamber simulation and reconstruction code in the MUON
39framework. The changes should have no side effects (mostly dummy arguments).
40(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
41of chambers with overlapping modules (MakePadHits, Disintegration).
42
802a864d 43Revision 1.3 2000/06/26 10:04:49 pcrochet
44problem with HP compiler solved (PH), static variables removed : now defined in AliMUONTriggerConstants
