Hello,
I have written a template class and I would like tot "assert the type". My class should only use floating point types like double or float. Can I do this check with BOOST_STATIC_ASSERT or anything else? The class need not to
E.g. #include <boost/static_assert.hpp> #include <boost/type_traits/is_floating_point.hpp> template<class Type> class real_holder { public: real_holder(Type val): _value(val) { BOOST_STATIC_ASSERT((is_floating_point<Type>::value)); } private: Type _value; }; ... { real_holder<double> rh_d(1.0); //OK. real_holder<int> rh_i(1); // compiletime error: boost::STATIC_ASSERTION_FAILURE<x> }
use a "countable type" (math: in N).
may be you need a different trait depending on the exact specification of your type. Joachim -- Interval Container Library [Boost.Icl] http://www.joachim-faulhaber.de
