Meaning of message count in core API.

[fwilson_adaptavist]

In:

            ClientSession coreSession = sf.createSession(false, true, true);
            ClientSession.QueueQuery result =
                    coreSession.queueQuery(new SimpleString(QUEUE_NAME));
            count = (int) result.getMessageCount();

Is message count the cumulative total of messages added to the queue since it was created or the number of currently undelivered messages?

This value never seems to go down despite me trying to acknowledge messages, etc. (Currently using 2.3.0.BETA1)

Thanks,

Frank

MessageCount is the number of currently undelivered messages.

MessagesAdded is the cumulative total of messages added to the queue since it was created.

When I reattempted what I was trying to do I could get message count to behave as I was expected. In particular I made sure to seting the ack batching in my consume/producer session to 0 .

i.e.

        session = sf.createSession(

                null, // user name

                null, // password

                false, // xa semantics

                true, // auto commit sends

                true, // auto commit acks

                false, // pre-ack

                0 // ack batch size

        );

By the way I could not find the MessagesAdded propery in the QueueQuery class, does this property come from somewhere else?
