What is boost archive?

The main concept of Boost. Serialization is the archive. An archive is a sequence of bytes that represent serialized C++ objects. Objects can be added to an archive to serialize them and then later loaded from the archive. In order to restore previously saved C++ objects, the same types are presumed.

What does boost serialization do?

When invoked for class data types, the class serialize function is invoked. Each serialize function is uses the above operators to save/load its data members. This process will continue in a recursive manner until all the data contained in the class is saved/loaded.

What is serialization and deserialization C++?

Serialization is a mechanism to convert an object into a sequence of bytes so that it can be stored in memory. The reverse of serialization is called deserialization, where the data in the byte stream is used to reconstruct it to its original object form.

How do you serialize an object in C++?

Serialization means turning your object into binary data. While deserialization means recreating an object from the data. When serializing you are pushing bytes into an uint8_t vector. When unserializing you are reading bytes from an uint8_t vector.

Why do you need to override UObject :: serialize?

If custom behavior is required, the UObject::Serialize function can be overridden. This can be useful to detect data errors, check version numbers, or perform automatic conversions or updates if the data format has changed.

What is serialization of string?

Serialization means to convert an object into that string, and deserialization is its inverse operation (convert string -> object). When transmitting data or storing them in a file, the data are required to be byte strings, but complex objects are seldom in this format.

How do I create an archive in boost?

The class boost::archive::text_oarchiveserializes data as a text stream, and the class boost::archive::text_iarchiverestores data from such a text stream. To use these classes, include the header files boost/archive/text_iarchive.hppand boost/archive/text_oarchive.hpp. Constructors of archives expect an input or output stream as a parameter.

How to serialize a text stream in boost?

The class boost::archive::text_oarchive serializes data as a text stream, and the class boost::archive::text_iarchive restores data from such a text stream. To use these classes, include the header files boost/archive/text_iarchive.hpp and boost/archive/text_oarchive.hpp. Constructors of archives expect an input or output stream as a parameter.

How is regenerated code generated in archives boost?

Code to save and load data to archives is regenerated for each combination of archive class and data type. Under these cirumstances, a good optimizing compiler that can expand inline functions to enough depth will generate fast code. However: Much inline code may be replicated.

Which is the boost class version in 64.7?

The macro BOOST_CLASS_VERSION assigns a version number to a class. The version number for the class animal in Example 64.7 is 1. If BOOST_CLASS_VERSION is not used, the version number is 0 by default. The version number is stored in the archive and is part of it.
