Is there something like a is_specialization in Boost.Traits? Something
like:
template <typename TypeT, template<typename> class TemplateTypeT>
struct is_specialization
{
private:
template <typename T>
static char foo( TemplateTypeT<T>* );
static int foo( ... );
public:
enum { value = (sizeof(is_specialization::foo((TypeT*)0)) ==
sizeof(char)) } ;
};
It's very limited since it only supports a specific number of template
arguments. The number of template arguments could be passed, but it
would still cause problems with non-type template arguments. Any ideas?
Maybe something like:
BOOST_IS_SPECIALIZATION(type, templateType, signature)
called like:
BOOST_IS_SPECIALIZATION(myType, std::list, (typename, typename))
