Re: [Boost-users] large enum and native array indexing

I would say that the easiest way is to use the preprocessor. #define BOOST_PP_LOCAL_MACRO(n) template<> struct Position { static const size_t value = n - 1; }; #define BOOST_PP_LOCAL_LIMITS (1, MAX_OP) #include BOOST_PP_LOCAL_ITERATE() In Christ, Steven Watanabe

I think I wasn't clear enough: the 3rd party lib (which I can't change of course) provides, enum Op { OPone = 7, OPtwo = 9, OPthree = 45, OPfour = 7667 // there is no pattern in the names nor the numbers. }; // in fact, there are a hundred entries and I wished to generate from Op template<> struct Position<OPone> { static const int value = 0; } template<> struct Position< OPtwo > { static const int value = 1; } template<> struct Position< OPthree > { static const int value = 2; } template<> struct Position< OPfour > { static const int value = 2; } I suppose there is no way to automagically generate the template specs from the enum? regards,
