Detailed Description

template<typename Archive>
class Packer< Archive >

Packer serializes objects into ssrc::spread::detail::ByteBuffer instances (usually a ssrc::spread::Message instance).

Each object type must have a Boost serialize function or method defined (or load and save).

Parameters:

Archive The archive type to use for serialization.

Serializes an object into a buffer.

The type of the object is automatically inferred by the compiler. The object write starts at the current buffer offset. After the object is serialized, the buffer size is adjusted and its write offset advanced to the end of the buffer. The buffer must have enough room to hold the data written or an exception will be thrown (std::ios_base::failure).

Parameters:

obj	The object to serialize.
buffer	The buffer that will store the object.
archive_flags	Boost archive constructor flags.

Returns:: The number of bytes written.

Exceptions:

boost::archive::archive_exception	If there is an archive writing error.
std::ios_base::failure	If the stream buffer fails, most likely because the buffer doesn't have enough room to hold the data.
