19Strings compared instead of pointers
20
268b9c60 21Revision 1.16 2001/05/30 14:04:31 hristov
22Dynamic cast replaced (F.Carminati)
23
4154d3d8 24Revision 1.15 2001/05/25 06:47:16 hristov
25Bug 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)
26
3e225ff6 27Revision 1.14 2001/05/16 14:57:16 alibrary
28New files for folders and Stack
29
9e1a0ddb 30Revision 1.13 2001/05/09 01:00:19 nilsen
31Fixed up a typo in the cout of Init(). Now properly indecates which version
32of code is being used.
33
82140a73 34Revision 1.12 2001/04/18 12:06:02 barbera
35Number of modules in layer 5 and 6 re-set to 23 and 26
36
18c21458 37Revision 1.11 2001/03/23 00:12:23 nilsen
38Set Reading of AliITSgeom data from Geant3 common blocks as the default and
39not a .det file. Removed redundent calls to BuildGeometry.
40
0646a0e8 41Revision 1.10 2001/02/14 14:22:58 nilsen
42Now looking in the right director for the old .det.
43
202679a1 44Revision 1.9 2001/02/14 14:12:43 nilsen
45Forgot about the nonexisting v in ITSgeometry_5.det.
46
262d891d 47Revision 1.8 2001/02/14 14:06:23 nilsen
48Wrong default .det file name for old .det file format.
49
88cc8e8a 50Revision 1.7 2001/02/13 16:53:35 nilsen
51Fixed a but when trying to use GEANT4. Needed to replace
52if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC)))
53because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer
54did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed
55to fix a bug in the initilizers and a bug in BuildGeometry. This is now done
56in the same way as in AliITSv5.cxx.
57
9a4c6ea3 58Revision 1.6 2001/02/09 20:06:26 nilsen
59Fixed bug in distructor. Can't distroy fixxed length arrays. Thanks Peter.
