18 | Revision 1.20 2002/10/22 14:45:47 alibrary | |
19 | Introducing Riostream.h | |
20 | ||
21 | Revision 1.19 2002/10/14 14:57:08 hristov | |
22 | Merging the VirtualMC branch to the main development branch (HEAD) | |
23 | ||
24 | Revision 1.18.10.2 2002/08/30 15:45:54 alibrary | |
25 | Adding geant4vmc support | |
26 | ||
27 | Revision 1.18.10.1 2002/06/10 17:51:15 hristov | |
28 | Merged with v3-08-02 | |
29 | ||
30 | Revision 1.18 2001/05/30 16:15:47 fca | |
31 | Correct comparison wiht AliGeant3::Class() introduced. Thanks to I.Hrivnacova | |
32 | ||
33 | Revision 1.17 2001/05/30 15:55:35 hristov | |
34 | Strings compared instead of pointers | |
35 | ||
36 | Revision 1.16 2001/05/30 14:04:31 hristov | |
37 | Dynamic cast replaced (F.Carminati) | |
38 | ||
39 | Revision 1.15 2001/05/25 06:47:16 hristov | |
40 | 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) | |
41 | ||
42 | Revision 1.14 2001/05/16 14:57:16 alibrary | |
43 | New files for folders and Stack | |
44 | ||
45 | Revision 1.13 2001/05/09 01:00:19 nilsen | |
46 | Fixed up a typo in the cout of Init(). Now properly indecates which version | |
47 | of code is being used. | |
48 | ||
49 | Revision 1.12 2001/04/18 12:06:02 barbera | |
50 | Number of modules in layer 5 and 6 re-set to 23 and 26 | |
51 | ||
52 | Revision 1.11 2001/03/23 00:12:23 nilsen | |
53 | Set Reading of AliITSgeom data from Geant3 common blocks as the default and | |
54 | not a .det file. Removed redundent calls to BuildGeometry. | |
55 | ||
56 | Revision 1.10 2001/02/14 14:22:58 nilsen | |
57 | Now looking in the right director for the old .det. | |
58 | ||
59 | Revision 1.9 2001/02/14 14:12:43 nilsen | |
60 | Forgot about the nonexisting v in ITSgeometry_5.det. | |
61 | ||
62 | Revision 1.8 2001/02/14 14:06:23 nilsen | |
63 | Wrong default .det file name for old .det file format. | |
64 | ||
65 | Revision 1.7 2001/02/13 16:53:35 nilsen | |
66 | Fixed a but when trying to use GEANT4. Needed to replace | |
67 | if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC))) | |
68 | because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer | |
69 | did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed | |
70 | to fix a bug in the initilizers and a bug in BuildGeometry. This is now done | |
71 | in the same way as in AliITSv5.cxx. | |
72 | ||
73 | Revision 1.6 2001/02/09 20:06:26 nilsen | |
74 | Fixed bug in distructor. Can't distroy fixxed length arrays. Thanks Peter. | |
75 | ||
76 | Revision 1.5 2001/02/09 00:05:31 nilsen | |
77 | Added fMajor/MinorVersion variables and made other changes to better make | |
78 | use of the new code changes in AliITSgeom related classes. | |
79 | ||
80 | Revision 1.4 2001/02/02 23:57:29 nilsen | |
81 | Added include file that are no londer included in AliITSgeom.h | |
82 | ||
83 | Revision 1.3 2001/01/30 09:23:13 hristov | |
84 | Streamers removed (R.Brun) | |
85 | ||
86 | Revision 1.2 2000/11/30 11:13:11 barbera | |
