- Do a static trait test on type to check for virtual serializability.

-
template<typename T, typename SerializerT, typename _enabled = void>struct checkpoint::ReconstructAsVirtualIfNeeded
- Do a static trait test on type to check for virtual serializability. If virtually serializable, we need to perform some extra work to register the type, allocate, and construct the proper type. Otherwise, we go through the normal path for allocating memory for T and serializing what the pointer points to.

Function documentation
template<typename T, typename SerializerT>
void virtualSerialize(T*& base,
SerializerT& s)
A function to handle serialization of objects of a mix of types in a virtual inheritance hierarchy.
This will automatically record the exact derived type at serialization, and reconstruct objects accordingly at deserialization.
template<typename SerializerT, typename T>
void reconstructPointedToObjectIfNeeded(SerializerT& s,
T*& target)
Allocate and construct memory for a pointer with type T.
| Parameters | |
|---|---|
| s in | the serializer |
| target in | a reference to a pointer to the target object |
This function automatically handles allocating and constructing the right type for virtually serialized pointers or non-virtual static allocation and construction.
An example of how to use this to properly serialize a std::shared_ptr<T>:
template <typename t>=""> struct X { std::shared_ptr<T> a;
template <typename serializert>=""> void serialize(SerializerT& s) { T* raw = elm.get(); checkpoint::reconstructPointedToObjectIfNeeded(s, raw); if (s.isUnpacking()) { a = std::shared_ptr<T>(raw); } s | *a; } };
