[Boost-users] [serialization] How to get hold of parent class in serialization hierachy

15 Mar 2008

      I have a structure like:

class A
{
	int m_position;
	int m_value;

	template<class Archive>
	void save(Archive & ar, const unsigned int version) const
	{
		ar & BOOST_SERIALIZATION("pos", m_position);

		B* b = somehow_get_hold_of_my_object_of_class_B;

		int temp = b->convertToSerializedFormat(m_value);
		ar & BOOST_SERIALIZATION("value", temp);
	}

	template<class Archive>
	void load(Archive & ar, const unsigned int version)
	{
		ar & BOOST_SERIALIZATION("pos", m_position);

		B* b = somehow_get_hold_of_my_object_of_class_B;

		int temp;
		ar & BOOST_SERIALIZATION("value", temp);
		m_value = b->convertFromSerializedFormat(temp);
	}
}

class B
{
	std::vector<A> m_vector;

	template<class Archive>
	void serialize(Archive & ar, const unsigned int version)
	{
		ar & BOOST_SERIALIZATION("posvalues", m_vector);
	}

	int convertToSerializedFormat(int value);
	int convertFromSerializedFormat(int value);

}

I could have a B* pointer in each of my A objects, but cannot afford that due to tough memory constraints.

So the issue is how to get hold of a B* pointer (which is the object that holds the vector of A objects) ??

TIA
