-Revision 1.20 2002/10/14 14:57:00 hristov
-Merging the VirtualMC branch to the main development branch (HEAD)
-
-Revision 1.18.8.1 2002/07/24 09:27:50 alibrary
-Updating on VirtualMC
-
-Revision 1.19 2002/05/31 21:07:42 mariana
-Fix memory leak
-
-Revision 1.18 2001/08/24 21:06:37 nilsen
-Added more documentation, fixed up some coding violations, and some
-forward declorations.
-
-Revision 1.17 2001/07/27 08:06:48 hristov
-Use global gRandom generator (M.Ivanov)
-
-Revision 1.16 2001/02/08 23:57:00 nilsen
-Fixed up some informational printouts.
-
-Revision 1.15 2001/02/07 20:23:21 nilsen
-Fixed bug with HP and no unget in iostream.h. Now using putback instead.
-Other changes and fixes also included.
-
-Revision 1.14 2001/02/03 00:00:29 nilsen
-New version of AliITSgeom and related files. Now uses automatic streamers,
-set up for new formatted .det file which includes detector information.
-Additional smaller modifications are still to come.
-
-Revision 1.11 2000/10/02 16:32:35 barbera
-Forward declaration added
-
-Revision 1.4.4.15 2000/10/02 15:52:05 barbera
-Forward declaration added
-
-Revision 1.10 2000/09/05 14:25:50 nilsen
-Made fixes for HP compiler. All function parameter default values placed
-in .h file. Fixed the usual problem with HP compilers and the "for(Int_t i..."
-business. Replaced casting (Double_t [3][3]) to (Double_t (*)[3]) for HP.
-Lastly removed all "const" before function parameters which were 2 dim. arrays,
-because on HP root generates some strange code (?). Thanks Peter for the
-changes.
-
-Revision 1.9 2000/08/29 20:19:03 nilsen
-Removed dependency on structure AliITSeomS and replaced it with class
-AliITSgeomMatrix. Added many new functions with many new arguments. Most
-in the form of in line functions for speed.
-
-Revision 1.4.4.6 2000/06/04 16:33:32 Nilsen
-A restructured AliITSgeom class. Now used AliITSgeomMatrix.
-
-Revision 1.4.4.5 2000/03/04 23:42:39 Nilsen
-Updated the comments/documentations and improved the maintainability of the
-code.
-
-Revision 1.4.4.4 2000/03/02 21:27:07 Nilsen
-Added two functions, SetByAngles and SetTrans.
-
-Revision 1.4.4.3 2000/01/23 03:09:10 Nilsen
-// fixed compiler warnings for new function LtLErrorMatrix(...)
-
-Revision 1.4.4.2 2000/01/19 23:18:20 Nilsen
-Added transformations of Error matrix to AliITSgeom and fixed some typos
-in AliITS.h and AliITShitIndex.h
-
-Revision 1.4.4.1 2000/01/12 19:03:32 Nilsen
-This is the version of the files after the merging done in December 1999.
-See the ReadMe110100.txt file for details
-
-Revision 1.4 1999/10/15 07:03:20 fca
-Fixed bug in GetModuleId(Int_t index,Int_t &lay,Int_t &lad, Int_t &det) and
-a typo in the creator. aliroot need to be rerun to get a fixed geometry.
-
-Revision 1.3 1999/10/04 15:20:12 fca
-Correct syntax accepted by g++ but not standard for static members, remove minor warnings
-
-Revision 1.2 1999/09/29 09:24:20 fca
-Introduction of the Copyright and cvs Log
