[rabbitmq-discuss] custom exchange checking auth user

[Dmitry Andrianov]

Understood.

One more question: some time ago I was told that either custom exchange 
or decorator will both serve for my purpose.
However while with exchange if I return empty list from route callback, 
no routing happens, the same does not seem to work in decorator.
Reading Erlang in rabbit_exchange.erl is very hard for me so I can be 
wrong but it looks like whatever decorator returns from route is only 
appended to the list of destinations and decorator cannot override the 
ones selected by exchange.

Is it correct? What is the correct way to deny processing message in the 
decorator?

And is there a recommended best practice for what should be used for 
validation purposes - custom exchange or exchange decorator?

Many thanks.
Dmitry
