d88f97cc 1//*CMZ : 1.00/02 04/07/97 16.48.20 by Nick van Eijndhoven (UU/CERN)
2//*-- Author : Nick van Eijndhoven (UU/CERN) 04/07/97
4// History of updates //
604-jul-1997 NvE First release of the package
711-jul-1997 NvE Class Invmass added to /GENUTILS and directories /PHYSICS
8 and /TRACKING created to hold Jet and Track classes resp.
915-aug-1997 NvE Pilot patch *RALICE removed and automatic installation
10 now completely performed by pure CMZ commands in the
11 INSTALL macro.
1212-sep-1997 NvE Signal of central cluster module and position in user
13 coordinates for all modules introduced in the Calorimetry
14 package.
15 Also all "float vec[]" replaced by "float* vec" in the
16 Lorbo class for stylistic reasons.
1720-sep-1997 NvE Name of member function "getc()" of Calorimeter changed to
18 "get_c()" to avoid clash with native C function.
19 Also protection added in Calorimeter::group() against cases
20 where no modules fired.
2123-sep-1997 NvE Macro "install" modified to also enable automatic installation
22 of a G++ or ROOT loadable shared library 'ralice.sl'.
2324-sep-1997 NvE Class "Calorimeter" optimized by introduction of pointers
24 for the Module matrix instead of an indexed array.
2526-sep-1997 NvE Directory /ROOT added to hold the universal ROOT dictionaries
26 (dict.h and dict.cc) as generated by "rootcint" for all the
27 classes of this RALICE package.
28 This will allow automatic installation of the RALICE library
29 without running "rootcint".
3030-sep-1997 NvE 2-body decay added to class Track and invokation of "delete []"
31 only performed in case the object exists in the destructors
32 of the Calorimeter, Jet and Track classes.
3302-oct-1997 NvE Installation for MSVC++ added into macro "install" and several
34 "return 0.;" statements added in some "Sample" member functions.
35 The latter caused MSVC++ compiler errors.
36 Also 'int ..=fabs(int..)' changed to 'int ..=int(fabs(int..))'
37 in "Cluster::Add()" to prevent G++ warning.
3803-oct-1997 NvE The above code is now ANSI compatible, but MSVC++ 5.0 still
39 gives an error when comp. extensions are switched off (flag /Za).
40 The reason is probably an incorrect implementation of the ANSI
41 type conversion rules in MSVC++. To satisfy MSVC++ for the moment
42 the code in in "Cluster::Add()" has been changed to
43 'int ..=int(fabs(double(int..)))' so that at least a Microsoft
44 compatible RALICE.DLL can be produced. As soon as G++ is able
45 to produce Microsoft compatible dll's the support for MSVC++
46 will be dropped for ralice.cmz.
47 Message to all : USE G++ AS COMPILATION STANDARD !
48 Also CMZ standard adopted to include a "$" in the DECK names
49 which contain KEEP definitions.
5013-oct-1997 NvE Compiler directive for g++ changed in "flogon" and "install"
51 to provide warning for each non-ANSI C++ statement.
52 Also ROOT libs linked with g++ in "install" in case of
53 ROOT loadable shared library creation.
54 Unused variables removed in "Calorimeter::add_ring" and
55 "Track::decay".
5614-oct-1997 NvE Strict ANSI requirements dropped for ROOT loadable lib creation
57 to avoid many harmless warnings from rootcint generated code.
58 Class "Random" added to /GENUTILS and /ROOT updated accordingly.
5914-oct-1997 NvE Class "Random" extended with user definable distribution and
60 /ROOT updated accordingly.
6119-oct-1997 NvE Class "Random" extended with vector facility for user
62 defined dist. and also bug fixed. /ROOT updated accordingly.
6327-oct-1997 NvE Class "Random" optimised for user definable distribution and
64 /ROOT updated accordingly.

67 of this package together with other packages.
6820-jan-1998 NvE New ralicedict produced because of new ROOT 1.03/09 version.
6923-mar-1998 NvE Macro "install" modified to support HP-CC.
70 Multiple usage of for-loop index names removed to satisfy HP-CC
71 compiler (although the original code was ANSI C++).
72 Cluster data just reset to 'empty cluster' in case of cluster
73 'creation' or 'start' for edge module or no-signal module.
7431-mar-1998 NvE Array index bug fixed in class Jet.
7503-apr-1998 NvE Jet and Invmass classes optimised by using pointers and
76 compiler options /GD and /DWIN32 introduced for msvc++
77 in order to optimize for windows DLL's and ensure correct
78 pre-processing in RConfig.h for ROOT library creation.
7913-apr-1998 NvE ROOTCINT processing implemented in $KUMACS/INSTALL and
80 contents of /ROOT updated accordingly.
81 Class Vertex added to /TRACKING and classes Track and Jet
82 protected against modifying of returned addresses.
8314-apr-1998 NvE "rm .def" removed for Unix systems in $KUMACS/INSTALL since
84 on Unix no .def file is created by ROOTCINT.
8517-apr-1998 NvE Return type Track& changed to Track* in the get_trk()
86 member functions of the Jet and Vertex classes.
8721-apr-1998 NvE Classes Track, Vertex, Jet, Lorbo and Invmass derived from
88 TObject to enable ROOT I/O.
89 $KUMACS/FLOGON and $KUMACS/INSTALL updated accordingly.

95 to allow direct I/O.
9603-jun-1998 NvE MSVC++ compiler option /DWIN32 removed in $KUMACS/INSTALL
97 because of bug fix in ROOT version 2.00.
98 Printout of version number introduced in $KUMACS/FLOGON and
99 DOC section updated for new email and www address.
10017-aug-1998 NvE New ALICE coding conventions adopted and automatic marking
101 of 'edge modules' introduced in class AliCalorimeter.
102 The automatic treatment of edge modules required new member-
103 functions EdgeUp() and EdgeDown() in class AliModule.
10419-aug-1998 NvE Call to LoadMatrix() added in AliCalorimeter::Group()
105 to correctly treat different event sizes (i.e. empty events)
106 when reading data from input file(s).
10725-aug-1998 NvE AliCalorimeter::GetModule() introduced to provide quick
108 access to all 'fired' modules.
10927-aug-1998 NvE GetSignal() and GetClusteredSignal() of AliModule now
110 return 0 in case the module was marked as dead.
111 Because of the above, protection against row=col=0
112 introduced in AliCalorimeter::Group().
113 To enable access of modified calorimeter module data via
114 AliCalorimeter::GetModule() after reading in, the "fModules"
115 elements are updated in AliCalorimeter::LoadMatrix().
11616-sep-1998 NvE Correct deletion of the module matrix introduced in the
117 AliCalorimeter destructor and AliCalorimeter::LoadMatrix().
11816-oct-1998 NvE New ALICE coding conventions adopted. This resulted in
119 modifications in /$KUMACS and /ROOT (.cxx extension instead of .cc)
120 and /HEADERS (public class area in front of private).

129 Also AliRandom derived from TObject to enable ROOT I/O.
13026-oct-1998 NvE DrawModules() and DrawClusters() histogram axes defined such
131 that the X and Y axis corresponds to columns and rows resp.
132 in AliCalorimeter. This view matches the 'common sense'.
13306-nov-1998 NvE SetDirectory(0) invoked for the histos created in
134 DrawModules() and DrawClusters() to suppress global character
135 of the histo pointer.
13616-nov-1998 NvE New class AliMath implemented in /GENUTILS and /ROOT
137 updated accordingly.

146 and AliSignal, AliCluster and AliVertex all derived from AliPosition.
147 AliModule inherits from AliSignal and arguments of SetPosition()
148 and GetPosition() in AliCalorimeter updated to match the AliSignal
149 inheritance of AliModule.
15011-mar-1999 NvE All types changed to Int_t, Float_t etc... in order to guarantee
151 portability of all data within the ROOT framework.

185 AliBoost.
18624-sep-1999 NvE In Ali4Vector internally the Lorentz invariant (x^mu x_mu) is now stored
187 instead of the scalar part x^0. This will yield better precision and
188 e.g. automatically conserves the particle identity (mass) in elastic
189 collisions.
19008-oct-1999 NvE GetResultError() introduced in Ali3Vector to provide error information

223 for AliCalcluster.
f40f8fbd 22418-jan-2000 NvE AliCalorimeter updated to remove memory leak and to enable event mixing.
225 Module and position pointers and various attributes (like edge values etc...)
226 are now saved in separate matrices for the complete calorimeter.
227 AliCalmodule and AliCalcluster updated accordingly and also cleaned up
228 a little to remove unneeded datamembers.
22903-mar-2000 NvE AliCalorimeter::SetSignal() updated to provide position for new modules
230 and AliCalorimeter::AddSignal() updated to invoke AliCalorimeter::SetSignal()
231 in case of new modules instead of having duplicate code.
232 (Thanks to Eugene van der Pijll).
