19Strings compared instead of pointers
20
268b9c60 21Revision 1.11 2001/05/30 14:04:31 hristov
22Dynamic cast replaced (F.Carminati)

4154d3d8 24Revision 1.10 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 1.9 2001/04/18 12:07:37 barbera
28Number of modules in layer 5 and 6 re-set to 23 and 26
29
18c21458 30Revision 1.8 2001/03/23 00:12:23 nilsen
31Set Reading of AliITSgeom data from Geant3 common blocks as the default and
32not a .det file. Removed redundent calls to BuildGeometry.
33
0646a0e8 34Revision 1.7 2001/02/13 16:53:35 nilsen
35Fixed a but when trying to use GEANT4. Needed to replace
36if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC)))
37because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer
38did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed
39to fix a bug in the initilizers and a bug in BuildGeometry. This is now done
40in the same way as in AliITSv5.cxx.
41
9a4c6ea3 42Revision 1.6 2001/02/09 20:06:26 nilsen
43Fixed bug in distructor. Can't distroy fixxed length arrays. Thanks Peter.
