25 | Revision 1.65 2001/11/27 16:27:28 nilsen |
26 | Adding AliITSDigitizer class to do merging and digitization . Based on the |
27 | TTask method. AliITSDigitizer class added to the Makefile and ITSLinkDef.h |
28 | file. The following files required minor changes. AliITS, added functions |
29 | SetHitsAddressBranch, MakeBranchInTreeD and modified MakeBranchD. |
30 | AliITSsimulationSDD.cxx needed a Tree indepenent way of returning back to |
31 | the original Root Directory in function Compress1D. Now it uses gDirectory. |
