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 turi::oarchive), in the form of a standard input stream, you can construct an iarchive object by:

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

For instance, to deserialize from a file,

std::ifstream fin("inputfile.bin");
turi::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 core/storage/serialization/serialization_includes.hpp

Constructor & Destructor Documentation

iarchive()

turi::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.

Definition at line 75 of file iarchive.hpp.

Member Function Documentation

read()

void turi::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"

Definition at line 103 of file iarchive.hpp.

read_into()

template<typename T >

void turi::iarchive::read_into ( T &  c )

inline

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

Definition at line 118 of file iarchive.hpp.
