18 Revision 1.37 2002/10/22 14:45:47 alibrary
19 Introducing Riostream.h
21 Revision 1.36 2002/10/14 14:57:08 hristov
22 Merging the VirtualMC branch to the main development branch (HEAD)
24 Revision 1.35.10.2 2002/08/30 15:45:54 alibrary
25 Adding geant4vmc support
27 Revision 1.35.10.1 2002/06/10 17:51:15 hristov
30 Revision 1.35 2001/05/30 16:15:47 fca
31 Correct comparison wiht AliGeant3::Class() introduced. Thanks to I.Hrivnacova
33 Revision 1.34 2001/05/30 15:55:35 hristov
34 Strings compared instead of pointers
36 Revision 1.33 2001/05/30 14:04:31 hristov
37 Dynamic cast replaced (F.Carminati)
39 Revision 1.32 2001/03/23 00:12:23 nilsen
40 Set Reading of AliITSgeom data from Geant3 common blocks as the default and
41 not a .det file. Removed redundent calls to BuildGeometry.
43 Revision 1.31 2001/02/13 16:53:35 nilsen
44 Fixed a but when trying to use GEANT4. Needed to replace
45 if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC)))
46 because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer
47 did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed
48 to fix a bug in the initilizers and a bug in BuildGeometry. This is now done
49 in the same way as in AliITSv5.cxx.
51 Revision 1.30 2001/02/09 20:06:26 nilsen
52 Fixed bug in distructor. Can't distroy fixxed length arrays. Thanks Peter.
54 Revision 1.29 2001/02/09 00:05:31 nilsen
55 Added fMajor/MinorVersion variables and made other changes to better make
56 use of the new code changes in AliITSgeom related classes.
58 Revision 1.28 2001/02/02 23:57:28 nilsen
59 Added include file that are no londer included in AliITSgeom.h
61 Revision 1.27 2001/01/30 09:23:13 hristov
62 Streamers removed (R.Brun)
64 Revision 1.26 2000/11/30 11:13:11 barbera
65 Added changes suggested by Federico Carminati on nov, 30, 2000
67 Revision 1.25 2000/10/05 20:50:00 nilsen
68 Now using root generated streamers.
70 Revision 1.14.4.12 2000/10/02 16:04:03 barbera
71 Forward declarations added
73 Revision 1.22 2000/07/10 16:07:19 fca
74 Release version of ITS code
76 Revision 1.14.4.4 2000/05/19 10:10:21 nilsen
77 fix for bug with HP and Sun unix + fix for event display in ITS-working branch
79 Revision 1.14.4.3 2000/03/04 23:46:38 nilsen
80 Fixed up the comments/documentation.
82 Revision 1.14.4.2 2000/03/02 21:53:02 nilsen
83 To make it compatable with the changes in AliRun/AliModule.
85 Revision 1.14.4.1 2000/01/12 19:03:33 nilsen
86 This is the version of the files after the merging done in December 1999.
87 See the ReadMe110100.txt file for details
