f1888ca5 | 18 | Revision 1.1 2001/11/27 16:27:28 nilsen |
19 | Adding AliITSDigitizer class to do merging and digitization . Based on the | |
20 | TTask method. AliITSDigitizer class added to the Makefile and ITSLinkDef.h | |
21 | file. The following files required minor changes. AliITS, added functions | |
22 | SetHitsAddressBranch, MakeBranchInTreeD and modified MakeBranchD. | |
23 | AliITSsimulationSDD.cxx needed a Tree indepenent way of returning back to | |
24 | the original Root Directory in function Compress1D. Now it uses gDirectory. | |
25 | ||
26 | Revision 1.2 2002/03/01 E. Lopez | |
27 | Diditization changed to start from SDigits instead of Hits. | |
28 | The SDigits are reading as TClonesArray of AliITSpListItem | |
