ff0e455e 18Revision 1.67 2002/03/15 17:22:51 nilsen
19Intoduced SDigits2Digits and SDigitsToDigits functions.
20
e0fc0305 21Revision 1.66 2001/11/28 01:35:45 nilsen
22Using standard constructors instead of default constructors for Clusterfinder,
23Response, and FastSimulator.
24
aa044888 25Revision 1.65 2001/11/27 16:27:28 nilsen
26Adding AliITSDigitizer class to do merging and digitization . Based on the
27TTask method. AliITSDigitizer class added to the Makefile and ITSLinkDef.h
28file. The following files required minor changes. AliITS, added functions
29SetHitsAddressBranch, MakeBranchInTreeD and modified MakeBranchD.
30AliITSsimulationSDD.cxx needed a Tree indepenent way of returning back to
31the original Root Directory in function Compress1D. Now it uses gDirectory.
