Hi,
Im 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;
public:
.....
};
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 >
which I want to serialize but as it can be seen I dont 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 dont know how is its
correct way of use. Can anybody give me a hint about how I can handle this
problem?
Just to add some restriction:
- I dont 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 dont 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
dependency
Thanks,
Pooyan.
