boost::shared_ptr< Buffer > cygnal::AMF::encodeElement ( boost::shared_ptr< cygnal::Element > el ) [static]

Encode an Element to its serialized representation.

Write an AMF element.

Parameters:

el

A smart pointer to the Element to encode.

Returns:: a binary AMF packet in big endian format

This encodes the data supplied to an AMF formatted one. As the memory is allocatd within this function, you *must* free the memory used for each element or you'll leak memory.

A "packet" (or element) in AMF is a byte code, followed by the data. Sometimes the data is prefixed by a count, and sometimes it's terminated with a 0x09. Ya gotta love these flaky ad-hoc formats.

All Numbers are 64 bit, big-endian (network byte order) entities.

All strings are in multibyte format, which is to say, probably normal ASCII. It may be that these need to be converted to wide characters, but for now we just leave them as standard multibyte characters. Encode an Element to it's serialized representation.

Parameters:

el

A smart pointer to the Element to encode.

Returns:: a binary AMF packet in big endian format
