18 Revision 1.11 2001/05/30 14:04:31 hristov
19 Dynamic cast replaced (F.Carminati)
21 Revision 1.10 2001/05/25 06:47:16 hristov
22 Bug fix in the creation of the AliITSgeom::fShape entry for SPD. Now there is both a proper shape entry and a default, should there be future changes. This bug was related to fMinorVersion=3 was not antisipated. (B.Nilsen)
24 Revision 1.9 2001/04/18 12:07:37 barbera
25 Number of modules in layer 5 and 6 re-set to 23 and 26
27 Revision 1.8 2001/03/23 00:12:23 nilsen
28 Set Reading of AliITSgeom data from Geant3 common blocks as the default and
29 not a .det file. Removed redundent calls to BuildGeometry.
31 Revision 1.7 2001/02/13 16:53:35 nilsen
32 Fixed a but when trying to use GEANT4. Needed to replace
33 if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC)))
34 because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer
35 did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed
36 to fix a bug in the initilizers and a bug in BuildGeometry. This is now done
37 in the same way as in AliITSv5.cxx.
39 Revision 1.6 2001/02/09 20:06:26 nilsen
40 Fixed bug in distructor. Can't distroy fixxed length arrays. Thanks Peter.
42 Revision 1.5 2001/02/09 00:05:31 nilsen
43 Added fMajor/MinorVersion variables and made other changes to better make
44 use of the new code changes in AliITSgeom related classes.
46 Revision 1.4 2001/02/02 23:57:29 nilsen
47 Added include file that are no londer included in AliITSgeom.h
49 Revision 1.3 2001/01/30 09:23:13 hristov
50 Streamers removed (R.Brun)
52 Revision 1.2 2000/11/30 11:13:11 barbera
53 Added changes suggested by Federico Carminati on nov, 30, 2000
55 Revision 1.1 2000/10/07 15:46:29 barbera
56 Version 5 of the geometry with symmetric services
58 Revision 1.25 2000/10/05 20:50:00 nilsen
59 Now using root generated streamers.
61 Revision 1.14.4.12 2000/10/02 16:04:03 barbera
62 Forward declarations added
64 Revision 1.22 2000/07/10 16:07:19 fca
65 Release version of ITS code
67 Revision 1.14.4.4 2000/05/19 10:10:21 nilsen
68 fix for bug with HP and Sun unix + fix for event display in ITS-working branch
70 Revision 1.14.4.3 2000/03/04 23:46:38 nilsen
71 Fixed up the comments/documentation.
73 Revision 1.14.4.2 2000/03/02 21:53:02 nilsen
74 To make it compatable with the changes in AliRun/AliModule.
76 Revision 1.14.4.1 2000/01/12 19:03:33 nilsen
77 This is the version of the files after the merging done in December 1999.
78 See the ReadMe110100.txt file for details
80 Revision 1.14 1999/10/22 08:16:49 fca
81 Correct destructors, thanks to I.Hrivnacova
83 Revision 1.13 1999/10/06 10:15:19 fca
84 Correct bug in allocation of layer name and add destructor
86 Revision 1.12 1999/10/05 08:05:09 fca
