25 :
26 : as already present in headers cppuhelper/implbase<1-12>.hxx and
27 : cppuhelper/compbase<1-12>.hxx.

29 : Don't use this header for interface numbers up to 12;
30 : always use the existing cppuhelper/(impl|comp)base<1-12>.hxx headers
31 : for this purpose, which eases debugging.

33 : Including this header requires a little discipline, because it has no
34 : include guards. Please use the following external include guard rule

39 : #define COMPHELPER_IMPLBASE_INTERFACE_NUMBER <N>
40 : #include <comphelper/implbase_var.hxx>
41 : #endif
42 :
43 : Additionally you can
44 :
45 : #define COMPHELPER_IMPLBASE_MAX_CTOR_ARGS <N>
46 :
47 : to control the maximum number of templated ctor arguments for the
48 : ImplInheritanceHelper<N> classes.
49 : The default is a maximum of 6 arguments.
