19Introducing Riostream.h
20
4ae5bbc4 21Revision 1.36 2002/10/14 14:57:08 hristov
22Merging the VirtualMC branch to the main development branch (HEAD)
23
b9d0a01d 24Revision 1.35.10.2 2002/08/30 15:45:54 alibrary
25Adding geant4vmc support
26
27Revision 1.35.10.1 2002/06/10 17:51:15 hristov
28Merged with v3-08-02
29
30Revision 1.35 2001/05/30 16:15:47 fca
31Correct comparison wiht AliGeant3::Class() introduced. Thanks to I.Hrivnacova
32
cbfdea0d 33Revision 1.34 2001/05/30 15:55:35 hristov
34Strings compared instead of pointers
35
268b9c60 36Revision 1.33 2001/05/30 14:04:31 hristov
37Dynamic cast replaced (F.Carminati)
38
4154d3d8 39Revision 1.32 2001/03/23 00:12:23 nilsen
40Set Reading of AliITSgeom data from Geant3 common blocks as the default and
41not a .det file. Removed redundent calls to BuildGeometry.
42
0646a0e8 43Revision 1.31 2001/02/13 16:53:35 nilsen
44Fixed a but when trying to use GEANT4. Needed to replace
45if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC)))
46because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer
47did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed
48to fix a bug in the initilizers and a bug in BuildGeometry. This is now done
49in the same way as in AliITSv5.cxx.
50
9a4c6ea3 51Revision 1.30 2001/02/09 20:06:26 nilsen
