Description

Applies element conversion to each element in a Forward Sequence. The resulting type is a Random Access Sequence that provides a converting constructor accepting the original type as its argument.

Header

#include <boost/fusion/support/deduce_sequence.hpp>

Synopsis

namespace traits
{
    template <class Sequence> 
    struct deduce_sequence
    {
        typedef unspecified type;
    };
}

Example

template <class Seq>
struct holder
{
    typename traits::deduce_sequence<Seq>::type element;

    holder(Seq const & a)
      : element(a)
    { }
};

template <typename T0, typename T1>
holder< vector<T0 const &, T1 const &> > 
make_holder(T0 const & a0, T1 const & a1)
{
    typedef vector<T0 const &, T1 const &> arg_vec_t;
    return holder<arg_vec_t>( arg_vec_t(a0,a1) ); 
}
