9 rootcint header_file[+][-][!] ... [LinkDef.h] > dict_file
10 rootcint [-f] dict_file [-c] header_file[+][-][!] ... [LinkDef.h]

13 The rootcint program generates the Streamer(), TBuffer &operator>>()
14 and ShowMembers() methods for ROOT classes, i.e. classes using the
15 ClassDef and ClassImp macros. In addition rootcint can also generate
16 the CINT dictionaries needed in order to get access to ones classes via
17 the interpreter.
18 rootcint can be used like:
20 rootcint TAttAxis.h[-][!] ... [LinkDef.h] > AxisGen.C
22 or
23 rootcint [-f] [AxDict.C] [-c] TAttAxis.h[-][!] ... [LinkDef.h]
24 The difference between the two is that in the first case only the
26 Streamer() and ShowMembers() methods are generated while in the latter
27 case a complete compileable file is generated (including the include
28 statements). The first method also allows the output to be appended to
29 an already existing file (using >> ). The optional minus behind the
30 include file name tells rootcint to not generate the Streamer() method.
31 A custom method must be provided by the user in that case. When using
32 option -c also the interpreter method interface stubs will be written
33 to the output file ( AxDict.C in the above case). By default the out‐
34 put file will not be overwritten if it exists. Use the -f (force)
35 option to overwite the output file.
36 Before specifying the first header file one can also add include file
38 directories to be searched and preprocessor defines, like:
39 -I$../include -DDebug
41 The (optional) file LinkDef.h looks like:
43 #ifdef __CINT__
45 #pragma link off all globals;
47 #pragma link off all classes;
48 #pragma link off all functions;
49 #pragma link C++ class TAxis;
51 #pragma link C++ class TAttAxis-;
52 #pragma link C++ class TArrayC-!;
53 #pragma link C++ function StrDup;
55 #pragma link C++ function operator+(const TString&,const TString&);
56 #pragma link C++ global gROOT;
58 #pragma link C++ global gEnv;
59 #pragma link C++ enum EMessageTypes;
61 #endif
63 This file tells rootcint for which classes the method interface stubs
65 should be generated. A trailing `-' in the class name tells rootcint to
66 not generate the Streamer() method. This is necessary for those classes
67 that need a customized Streamer() method. A trailing `!' in the class
68 name tells rootcint to not generate the operator>>(TBuffer &b, MyClass
69 *&obj) method. This is necessary to be able to write pointers to
70 objects of classes not inheriting from TObject. When this file is not
71 specified a default version exporting the classes with the names equal
72 to the include files minus the .h is generated.
73 IMPORTANT:
75 1 LinkDef.h must be the last argument on the rootcint command
77 line.
78 2 Note that the LinkDef file name MUST contain the string:
80 LinkDef.h or linkdef.h, i.e. NA49_LinkDef.h is fine just like,
81 mylinkdef.h.
