Re: [Boost-users] boost::serialization::array for Orocos RTT

Sorry, That's my mistake.This was boost1.61.Been trying out a lot of versions :). Anyways I found that boost1.54 had this template as array rest all have this array_wrapper.So Orocos RTT works out with Boost 1.54 only. On Wed, Aug 3, 2016 at 4:59 PM, Sambeet Panigrahi wrote:

Sir, I gave the following includes #include #include

I know boost::array exists,but does boost::serialization::array exist?Because in the namespace serialization in the boost/serialization/array.hpp, I could not find such a template.

namespace boost { namespace serialization {

// traits to specify whether to use an optimized array serialization

template <class Archive> struct use_array_optimization : boost::mpl::alwaysboost::mpl::false_ {};

So I try to make make_array a friend - but that doesn't // build. Need a C++ guru to explain this! template<class S> friend const boost::serialization::array_wrapper<T> make_array( T* t, S s);

array_wrapper(const array_wrapper & rhs) : m_t(rhs.m_t), m_element_count(rhs.m_element_count) {} public: array_wrapper(T * t, std::size_t s) : m_t(t), m_element_count(s) {}

// default implementation template<class Archive> void serialize_optimized(Archive &ar, const unsigned int, mpl::false_ ) const { // default implemention does the loop std::size_t c = count(); T * t = address(); while(0 < c--) ar & boost::serialization::make_nvp("item", *t++); }

T * address() const { return m_t; }

std::size_t count() const { return m_element_count; }

private: T * const m_t; const std::size_t m_element_count; };

template inline const array_wrapper< T > make_array( T* t, S s){ const array_wrapper< T > a(t, s); return a; }

} } // end namespace boost::serialization
