[zeromq-dev] endian conversions?

[Aamir M]

Hi Martin,

Sorry, I was confusing the ZMQ wire format with the user wire format. The
issue is that my own data (e.g. doubles) won't undergo endian conversion. I
think the solution is to use an encoding such as Google Protocol Buffers.
ZMQ will take care of endian conversion of the Protocol Buffers data, while
Protocol Buffers will take care of endian conversion of native datatypes
when it decodes to data sent over ZMQ.

I know from my experience with QPid that AMQP provides the user with a
Buffer class that has methods such as putDouble and getDouble, as well as
decode and encode methods that are supposed to automatically handle endian
conversion. But I guess that ZeroMQ is much lightweight and it is up to the
user to provide the wire format.

Thanks,
Aamir
