RE: [boost] Re: variant - is there an easy way to tell if an object is a variant at compile time?

-----Original Message----- From: boost-bounces@lists.boost.org [mailto:boost-bounces@lists.boost.org] On Behalf Of Eric Friedman

template <typename T> struct is_variant : mpl::false_ {};

template <BOOST_VARIANT_ENUM_PARAMS(typename T)> struct is_variant< variant<BOOST_VARIANT_ENUM_PARAMS(T)> > : mpl::true_ {};

should do the trick. If this is deemed useful, I can include it in the next release. For now, BOOST_VARIANT_ENUM_PARAMS should cover you.

Yes that's much better. I don't know why I was making it so difficult. Thanks!
