[Vortex] Question about ausage pattern

[Chris Yourch]

Since I wasn't sure of how unique the channel/msgno combination was I ended up keeping a per profile URI dictionary and keying into that with the channel and msgno.  Also, my framework tracks instance data for multiple host/port/profile-URI combinations so I had to have more keys to be unique.

Is the message-number guaranteed to be unique on a per channel basis?

BEEP is a standardized protocol (RFC 3340). Vortex couldn't make a
change like that or it wouldn't be BEEP anymore.

If you want a unique GUID for each message, just create a UUID at the
start of the connection, then for any given message concatenate its
channel number and message number onto the UUID. But personally I
think it's easier just to keep a per-connection dictionary whose keys
are {channel,message} number pairs; then the client can store anything
they want as the value.
