Subject: [Boost-users] Boost Serialization calling a custom serialize method
From: Pooyan Dadvand (pooyan_at_[hidden])

I’m trying to use the boost serialization in our project “Kratos” (a
Multi-physics finite element code) in which I found the following problem, I
have a class Variable which is derived from VariableData as follow:


Class VariableData


                std::size_t mKey;





template<class TDataType>

class Variable : public VariableData





Now I have a container which holds a pairs, consist of VariableData pointer
to the Variable and a void* pointer to its value:


std::vector<std::pair<const VariableData*, void*> >


which I want to serialize but as it can be seen I don’t have the pointer to
data in my variable and I might need to implement a costumized version of
Serialized with void* pValue as an additional parameter for VariableData and
Variable classes:


template<class TArchiveType>

Variable::serialize(TArchiveType &rArchive, const unsigned int Version,
void* pValue)


                rArchive & static_cast<TDataType>(pVAlue);



 The problem here is the template definition of this method which make it
impossible to be virtual. I note that the library uses
get_extended_type_info for this porposed. But I don’t know how is its
correct way of use. Can anybody give me a hint about how I can handle this


Just to add some restriction:

- I don’t want to add a hierarchy of handlers instead of pair
because it adds another pointer jump to the container and reduce its
performance in normal use of it

- I don’t want to add a version of non template members for each
archive type while it makes a lot of duplications and makes extra dependency
to the archive types in a layer of code which is not expected to have this
