Detailed Description

An input archive designed to load data saved using PortableBinaryOutputArchive.

This archive outputs data to a stream in an extremely compact binary representation with as little extra metadata as possible.

This archive will load the endianness of the serialized data and if necessary transform it to match that of the local machine. This comes at a significant performance cost compared to non portable archives if the transformation is necessary, and also causes a small performance hit even if it is not necessary.

It is recommended to use portable archives only if you know that you will be sending binary data to machines with different endianness.

The archive will do nothing to ensure types are the same size - that is the responsibility of the user.

When using a binary archive and a file stream, you must use the std::ios::binary format flag to avoid having your data altered inadvertently.

Warning

This archive has not been thoroughly tested across different architectures. Please report any issues, optimizations, or feature requests at the project github.

Parameters

data	The data to save
size	The number of bytes in the data

Template Parameters

DataSize

T The size of the actual type of the data elements being loaded
