MongoDB is a popular document database and boost::serialization a great
C++ marshalling library. Wouldn't it be even greater to patch these two
together? - This is where boost_mongo comes in.
boost_mongo serializes all your custom data types into mongo collections in
human readable format.
It can be used like any other boost archive and if your code already works with
xml archives, you are good to go.
Besides, the json_archives can be used for serialization to and from plain
JSON files.
The mongo archives can be used just like the boost xml archives. This means, that members need to be wrapped as name-value-pairs for serialization (see http://www.boost.org/doc/libs/1_54_0/libs/serialization/doc/wrappers.html#nvp for more detail).
This is a simple example, illustrating how boost_mongo serialization looks
like:
struct A
{
int a;
private:
friend class boost::serialization::access;
template<typename Archive>
void serialize(Archive& ar, unsigned int const)
{
ar & BOOST_SERIALIZATION_NVP(a);
}
};
// ...
A a;
mongo::BSONObjBuilder builder;
mongo_oarchive out(builder);
out << boost::serialization::make_nvp("myData", a);
// ...
The mongo_oarchive and mongo_iarchve expect a mongo::BSONObjBuilder and a
mongo::BSONObj, respectively. These containers can then be handled by the
mongo C++ client drivers.
boost_mongo passes all tests shipped with the boost distribution.
There are also many dedicated boost_mongo tests, including CI and code
coverage.
