template<
    typename T,
    typename Property>
struct can_query :
  public integral_constant< bool, automatically_determined >

Class template can_query is a trait that is derived from true_type if the expression boost::asio::query(std::declval<T>(), std::declval<Property>()) is well formed; otherwise false_type.
