Synchronization of Session with Sender and Receiver

[Jiri Krutil <ji...@krutil.com>]

Hi

I understand an AMQP session may only be used from one thread at a time.

How about Receiver and Sender objects created using a Session? To what  
extent are they associated with the parent session?

Is it possible to use a Sender or a Receiver in parallel with the  
parent Session from another thread? Or does the access to these  
objects have to be synchronized? If yes, which functions require  
synchronization?

Thanks
Jiri

An AMQP session is an ordered stream, but really at the level of the 
protocol the threading used in any particular implementation is not 
relevant.

On the whole, the messaging API allows for concurrent use of Sessions, 
Senders and Receivers. However some things may not make sense, e.g. 
concurrently closing a Session while sending over it, so usually 
applications will do some coordination between threads accessing these 
objects.
