I can't imagin how something like
m_offlineMode = true;
even compiles given that save is a "const" function.
If you can't live without this, it suggests that your saving operation
is altering the thing its saving - which would conflict with the
the idea that only one copy of anything is actually saved.
From looking at this - that's the only think I can ay.

I have the following two data structures:
std::map, jedox::util::CaseInsensitiv > m_LookupName;
std::map > m_LookupId;
Before serialization, the shared pointer - values of the maps do point to sth. meaningful.
Afterwards, however, they point to data-structures with meaningless content.
The keys (strings / ints) are serialized / unserialized correctly.
I guess its a general problem with serializing shared pointers contained in a std::map as values !?
BTW: the structures the shared pointers point to do have a serialization method themselves and I a
assume that it is called when serializing the map.
I serialize / unserialize as follows:
template<class Archive>
void save( Archive &ar, unsigned int version) const{
m_offlineMode = true;
bool oldCachedAll = m_CachedAll;
m_CachedAll = true;
ar & m_CachedAll;
ar & m_offlineMode;
// do not serialize the lock -- use the default constructor.
// we assume that no iterators that lock the cache do exist when serializing.
// ar & m_Lock;
ar & m_LookupId; // 1st structure
ar & m_LookupName; // 2nd structure
ar & m_SequenceNumber;
//reset old state for the case we want to continue working
m_CachedAll = oldCachedAll;
m_offlineMode = false;
}
template<class Archive>
void load( Archive &ar, unsigned int version) {
ar & m_CachedAll;
ar & m_offlineMode;
// do not serialize the lock -- use the default constructor.
// we assume that no iterators that lock the cache do exist when serializing.
// ar & m_Lock;
ar & m_LookupId;
ar & m_LookupName;
ar & m_SequenceNumber;
//reset old state for the case we want to continue working
}
kind regards, Oliver
