Detailed Description

The serialization input archive object which, provided with a reference to an istream, will read from the istream, providing deserialization capabilities.

Given a source of serialized bytes (written by an graphlab::oarchive), in the form of a standard input stream, you can construct an iarchive object by:

       // where strm is an istream object
       graphlab::iarchive iarc(strm);

For instance, to deserialize from a file,

       std::ifstream fin("inputfile.bin");
       graphlab::iarchive iarc(fin);

Once the iarc object is constructed, Serializable objects can be read from it using the >> stream operator.

        iarc >> a >> b >> c;

Alternatively, data can be directly read from the stream using the iarchive::read() and iarchive::read_char() functions.

For more usage details, see Serialization

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

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

Constructor & Destructor Documentation

graphlab::iarchive::iarchive ( std::istream &  instream )

inline

Constructs an iarchive object. Takes a reference to a generic std::istream object and associates the archive with it. Reads from the archive will read from the assiciated input stream.

Member Function Documentation

void graphlab::iarchive::read ( char *  c, size_t  l  )

inline

Directly reads a sequence of "len" bytes from the input stream into the location pointed to by "c"
