4154d3d8 | 18 | Revision 1.32 2001/03/23 00:12:23 nilsen |
19 | Set Reading of AliITSgeom data from Geant3 common blocks as the default and | |
20 | not a .det file. Removed redundent calls to BuildGeometry. | |
21 | ||
0646a0e8 | 22 | Revision 1.31 2001/02/13 16:53:35 nilsen |
23 | Fixed a but when trying to use GEANT4. Needed to replace | |
24 | if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC))) | |
25 | because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer | |
26 | did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed | |
27 | to fix a bug in the initilizers and a bug in BuildGeometry. This is now done | |
28 | in the same way as in AliITSv5.cxx. | |
29 | ||
9a4c6ea3 | 30 | Revision 1.30 2001/02/09 20:06:26 nilsen |
31 | Fixed bug in distructor. Can't distroy fixxed length arrays. Thanks Peter. | |
