ed9afcd2 | 18 | Revision 1.69 2002/05/05 21:06:55 nilsen |
19 | Added GetSimulationMoel, and fixed up SetDefaultSimulation to do the | |
20 | proper initilization when a simulation has already been defined. | |
21 | ||
54b8cf3b | 22 | Revision 1.68 2002/05/02 18:51:53 nilsen |
23 | AliITS.h | |
24 | Method MakeBranchR has now a second argument, with a default value: | |
25 | Option_t *opt=" ". Opt="Fast" is to create a separate branch | |
26 | for fast points in TreeR | |
27 | New method MakeBranchRF: it a separate branch in TreeR for Fast Points | |
28 | ||
29 | AliITS.cxx | |
30 | 1) TTree->Write() replaced with TTree->AutoSave for TreeS, TreeD and | |
31 | TreeR | |
32 | 2) Changes in MakeBranchR to allow the creation of a special branch | |
33 | for fast points | |

aa044888 | 42 | Revision 1.65 2001/11/27 16:27:28 nilsen |
43 | Adding AliITSDigitizer class to do merging and digitization . Based on the | |
44 | TTask method. AliITSDigitizer class added to the Makefile and ITSLinkDef.h | |
45 | file. The following files required minor changes. AliITS, added functions | |
46 | SetHitsAddressBranch, MakeBranchInTreeD and modified MakeBranchD. | |
47 | AliITSsimulationSDD.cxx needed a Tree indepenent way of returning back to | |
48 | the original Root Directory in function Compress1D. Now it uses gDirectory. | |
