To clarify further... You can put any arbitrary binary content into the
body of an AMQP message. William is illustrating how to use the AMQP
codec to safely encode typed data in binary form. Using the AMQP codec
allows you to not concern yourself with issues like endian-byte-order in
multi-byte integers.

Hi Wes,
It is possible. Unfortunately the only C++ example I can think of this is
currently in the management (QMF) code. I'll try to get another example out
soon.
Have a look here:
cpp/src/qpid/agent/ManagementAgentImpl.cpp
Simply, the steps are:
You create a Buffer and then use the various put APIs (e.g. putLong, putDouble
etc.) to put the binary types in the Buffer. You then place that Buffer in the
data portion of the message. On the consumer side you extract the Buffer and
then use the various get APIs (e.g. getLong, getDouble etc.) to retrieve the
values from the Buffer.
Best,
William

Is the Qpid C++ Client API capable of transferring binary data? It
seems like the only data type in qpid/client/Message.h is the
std::string (data field of TransferContent.h).
I am interested in transferring segments of binary data, and not ascii
strings. Is this possible with the current Qpid C++ API
implementation? I have not researched the AMQP protocol much yet, but
had assumed this would be possible with the wire protocol. If it is
not currently implemented, but it is possible, would it be as simple
as overridding the TransferContent and Message classes and working
backwards from there?
Thanks,
Wes
