Hi all,
I've been watching this thread with interest (partially in the hope
of an example as well!) An example of atomic update of direct
bindings does sound very interesting. Is it possible to get at this
from Java? (Pure JMS not a requirement).
Andrew,
yes, when you do the queue declare you mark the binding as
exclusive. Then additional bindings matching are atomically
replaced. This can be done from any client against the C++ broker
FieldTable args;
args.setInt("qpid.exclusive-binding",1);
//the following will cause the only binding from amq.direct with
'my-key' //to be the one to 'my-queue'; if there were any
previous bindings for that
//key they will be removed. This is atomic w.r.t message routing
through the
//exchange.
session.exchangeBind(arg::exchange="amq.direct", arg::queue="my-
queue",
arg::bindingKey="my-key", arg::arguments=args);
