Detailed Description

The serialization output archive object which, provided with a reference to an ostream, will write to the ostream, providing serialization capabilities.

Given a standard output stream, you can construct an oarchive object by:

// where strm is an ostream object

graphlab::oarchive oarc(strm);

For instance, to serialize to a file,

std::ofstream fout("outputfile.bin");

graphlab::oarchive oarc(fout);

Once the oarc object is constructed, Serializable objects can be written to it using the << stream operator.

oarc << a << b << c;

Alternatively, data can be directly written to the stream using the oarchive::write() function.

Written data can be deserialized using graphlab::iarchive. For more usage details, see Serialization

The oarchive object should not be used once the associated stream object is closed or is destroyed.

The oarc object does not flush the associated stream, and the user may need to manually flush the associated stream to clear any stream buffers. For instance, while the std::stringstream may be used for both output and input, it is necessary to flush the stream before all bytes written to the stringstream are available for input.

To use this class, include graphlab/serialization/serialization_includes.hpp
