The co::DataOStream/IStream has a serializer for std::vectors which serializes each element of the vector. You will however have to write serializers for the objects contained in the vector if they are not PODs or if they contain pointers, i.e.:

    co::DataOStream& operator << ( co::DataOStream& os, OSG::Node* node ) { ...; return os; }

You can commit()/sync() objects from any thread. sync is not threadsafe and needs an external lock (see API doc). sync does block if the version has not been commited yet.


HTH,
