Re: [Boost-users] Deriving Serialization classes
????
a) But I'm deriving it from text_archive_imp
b) what? I didn't understand.. As I said the binary serialization is
working fine
c) Onde again what do you mean?? How can I derivate the serialization classes??
I've tried the following code to, but with the same error:
class TextArchiveO : public IArchive,
// don't derive from text_oarchive !!!
public boost::archive::text_oarchive_impl<TextArchiveO>
{
public:
TextArchiveO(std::ostream & os, unsigned flags = 0) :
boost::archive::text_oarchive_impl<TextArchiveO>(os, flags)
{}
~TextArchiveO(){}
virtual void Serialize(int& t) { *this & BOOST_SERIALIZATION_NVP(t); }
virtual void Serialize(bool& t) { *this & BOOST_SERIALIZATION_NVP(t); }
};
class TextArchiveI : public IArchive,
// don't derive from text_oarchive !!!
public boost::archive::text_iarchive_impl<TextArchiveI>
{
public:
TextArchiveI(std::istream & is, unsigned flags = 0) :
boost::archive::text_iarchive_impl<TextArchiveI>(is,flags)
{}
~TextArchiveI(){}
virtual void Serialize(int& t) { *this & BOOST_SERIALIZATION_NVP(t); }
virtual void Serialize(bool& t) { *this & BOOST_SERIALIZATION_NVP(t); }
};

Sorry, I didn't see that - the IArchive threw me for a loop. Look for the explicit instantiation at the bottom of text_oarchive.cpp. Include something similar in your own code. Robert Ramey
Hummm.. good point.
But now I'm getting these compilation errors:
IT says that the functions template are already defined :S.
I wonder where.....

you've included *.ipp files twice. Once in TextSerializer.h and again in in your instantiation. The *.ipp files shouldn't be in the TextSerializer.h header Robert Ramey
So true! And so stupid of me.... LOL

Another thing!
I've settled that for text binary and xml archives.
Now I want a method that just saves data (binary to the file).
like
void Serialize(void* data, size_t size);
I mean I'm serializing an object but I want to store some data, just store it.
How can I make that? If it is a text or a xml file it's ok. You see
the other members of the object and the void * you see it but just
strange characters.
Thanks

Ok!!!
Now I'm getting unregistered_class exceptions when trying to seryalize
a class that has another class. Like:
class C : public Serializer
{
typedef Serializer Parent;
public:
std::string text;
A* m_owner;
int32 dasse;
C():m_owner(0)
{
text = "Ola sua puta rabeta!";
dasse = 69;
}
void Serialize(IArchive& ar, const unsigned int version)
{
ar.Serialize(dasse);
ar.Serialize(text);
//ar.Serialize(m_owner);
}
};
class A : public Serializer
{
typedef Serializer Parent;
public:
void Serialize(IArchive& ar, const unsigned int version)
{
ar.Serialize(dumbi);
ar.Serialize(vectorTest);
ar.Serialize(matrix);
ar.Serialize(testing);
ar.Serialize((void*)test_void, sizeof(Vector3f));
}
int dumbi;
float dumbf;
Vector2f vectorTest;
Matrix33 matrix;
C* testing;
Vector3f* test_void;
A():dumbi(12), dumbf(69.69f)
{
testing = new C();
testing->m_owner = this;
matrix.SetIdentity();
test_void = new Vector3f(1,2,3);
}
A(int dumb1, float dumb2) : dumbi(dumb1), dumbf(dumb2)
{
testing = new C();
testing->m_owner = this;
matrix.SetIdentity();
test_void = new Vector3f(1,2,3);
}
};
If I comment the line that serializes C object from A
(ar.Serialize(testing);) everything works fine.
I can serialize Object A. And I can serialiaze the Object C to. But
when I have apoibter to C on object A It throws the unregistered_class
exception?
Why?
How can I avoid this???

Just make the test without a pointer ant it works just fine.
I've looked at the documentation and it only refers to this problem on
derivated classes! But I'm not deriving any class. I'm just including
the ponter of a class :(

Anyone???
In the boost code I found this comment:
// note:if this exception is thrown, be sure that derived pointer
// is either regsitered or exported.
How can I register a class????????

Hello,

I hope this helps.
