Thread: Error: 'serialize' : illegal qualified name in member declaration

Feh, I'm trying to serialize a class and failing because of a curious error, heres the code:

Code:

#include <boost/archive/text_iarchive.hpp>
#include <boost/archive/text_oarchive.hpp>
#include <boost/serialization/base_object.hpp>


class CObject
{

public:
	CObject(){}

	virtual void Create()
	{}

	virtual void Access()
	{}

	virtual void Delete()
	{delete this;}

private:
	virtual void Save_to_Disk(std::string Filename)
	{}
	
	virtual void Read_File(std::string Filename)
	{}
	friend class boost::serialization::access;
	template<class Archive>
	virtual void boost::serialization::serialize(Archive & ar, const unsigned int version){};
};

Does anyone have any Idea what this means? I think it might have something to do with the template thing and the parameter Archive & ar, namespace issues perhaps?

Code:

	template<class Archive>
	virtual void boost::serialization::serialize(Archive & ar, const unsigned int version){};

The problem is here.
I don't think this means what you think it means.

In fact, what do you think it means?

Well, it looks like its declaring a template of type Archive... I guess the only trouble is I kinda expected boost to have one of these. I do find it strange that archive doesn't have anything in it. Maybe I need to define an archive class there? I'm honestly not sure what that code means because I'm trying to implement a part of boost I've never used before. But maybe you can tell me? That is why I'm here

The compiler thinks you're declaring a member template, and the name you're giving it isn't legal.

I don't know anything about Boost, so I'm not sure what exactly you're trying to accomplish. The only thing that I can think of might be that your friend class is expecting a callback method called serialize, in which case you should strip off the boost::serialization:: qualification.

Perhaps someone that is familiar with Boost can give you a better answer.

Nice, I changed the code a bit because I read more about how boost works with derived classes, so the new code is:

Code:

class CObject
{

public:
	CObject(){}

	virtual void Create()
	{}

	virtual void Access()
	{}

	virtual void Delete()
	{delete this;}

private:
	virtual void Save_to_Disk(std::string Filename)
	{}
	
	virtual void Read_File(std::string Filename)
	{}
	friend class boost::serialization::access;
	template<class Archive>
	void serialize(Archive & ar, const unsigned int version){};
};

Yeah, so you were right, I'm not familiar with callback methods, maybe I aught to read about those sometime.
