cbfdea0d | 18 | Revision 1.34 2001/05/30 15:55:35 hristov |
19 | Strings compared instead of pointers | |
20 | ||
268b9c60 | 21 | Revision 1.33 2001/05/30 14:04:31 hristov |
22 | Dynamic cast replaced (F.Carminati) | |
23 | ||
4154d3d8 | 24 | Revision 1.32 2001/03/23 00:12:23 nilsen |
25 | Set Reading of AliITSgeom data from Geant3 common blocks as the default and | |
26 | not a .det file. Removed redundent calls to BuildGeometry. | |
27 | ||
0646a0e8 | 28 | Revision 1.31 2001/02/13 16:53:35 nilsen |
29 | Fixed a but when trying to use GEANT4. Needed to replace | |
30 | if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC))) | |
31 | because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer | |
32 | did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed | |
33 | to fix a bug in the initilizers and a bug in BuildGeometry. This is now done | |
34 | in the same way as in AliITSv5.cxx. | |
35 | ||
9a4c6ea3 | 36 | Revision 1.30 2001/02/09 20:06:26 nilsen |
37 | Fixed bug in distructor. Can't distroy fixxed length arrays. Thanks Peter. | |
38 | ||
58e13d99 | 39 | Revision 1.29 2001/02/09 00:05:31 nilsen |
40 | Added fMajor/MinorVersion variables and made other changes to better make | |
41 | use of the new code changes in AliITSgeom related classes. | |
42 | ||
bae7e562 | 43 | Revision 1.28 2001/02/02 23:57:28 nilsen |
44 | Added include file that are no londer included in AliITSgeom.h | |
