[Boost-users] [serialization] how to serialize boost::function

15 Sep 2009

      Hello,

Is it possible to serialize the following class:

struct foo
{
	void f1(int a)
	{}
	void f2(const std::string& s)
	{}

                void init()
                {
		using boost::bind;
		functors_.push_back(bind(&foo::f1, this, 1));
		functors_.push_back(bind(&foo::f2, this, "test"));
                }

	std::vector<boost::function<void(void)> > functors_;
};

That is, I'd like save the functors, in order to run them later, when
the object is loaded from the archive.

A straightforward attempt fails:

struct foo
{
//......
	friend class boost::serialization::access;
	template<class Archive>	void serialize(Archive &ar, const unsigned int version)
	{
		ar & BOOST_SERIALIZATION_NVP(functors_);
	}
};
