Re: [Boost-users] How to I specify boost::fusion::vector<something> as the type of an argument?

Hi,

template <typename T, typename R> class A;

I would like a template function, whose argument should be of the type like.

boost::fusion::vector<A<T, R1>, A<T, R2>,...>

I would use something like this: template <class T> enable_if<is_vector_of_A_T_R<T> >::type foo(const T& arg) { ... } Where is_vector_of_A_T_R<T> is a metafunction, that returns true iif T is a fusion::vector of desired structure. Roman Perepelitsa.
