e0fc0305 18Revision 1.66 2001/11/28 01:35:45 nilsen
19Using standard constructors instead of default constructors for Clusterfinder,
20Response, and FastSimulator.
21
aa044888 22Revision 1.65 2001/11/27 16:27:28 nilsen
23Adding AliITSDigitizer class to do merging and digitization . Based on the
24TTask method. AliITSDigitizer class added to the Makefile and ITSLinkDef.h
25file. The following files required minor changes. AliITS, added functions
26SetHitsAddressBranch, MakeBranchInTreeD and modified MakeBranchD.
27AliITSsimulationSDD.cxx needed a Tree indepenent way of returning back to
28the original Root Directory in function Compress1D. Now it uses gDirectory.
