Proton-J get "first" field from disposition frame
Hi all,
I'm attempting to get the delivery id or "first" field from a disposition that my client receives after it sends a message. I'm using Proton-J and the Reactor. I can see that the disposition frame comes in and that the "first" field matches the deliveryId and deliveryTag of the sent message. The onDelivery callback fires and I'm able to get the Delivery, but it seems as though at this point the only place the deliveryId exists is within a private TransportDelivery object that cannot be accessed.
Any guidance would be helpful.
Thanks,
Andrew

Gotcha. That works, thanks!
Although it would seem to me that there is no harm in exposing the id/tag, just for reading.

I haven't used the reactor bits, but I'd guess this is the same....when using the engine 'directly' the Delivery object(s) updated and referred to by the delivery event(s) corresponds to the the message(s) that the disposition acted upon, i.e the transport has already done the matching for you, which I'd guess is one reason the API doesn't expose the deliveryId, coupled with the delivery-tag being a more relevant marker for application use.

So if I'm sending multiple messages, I'd like to be able to know which message a particular disposition frame corresponds to. And, correct me if I'm wrong (perhaps I'm thinking about this wrong), right now the only thing I'd be able to do is count how many dispositions come back. I'm able to get the remote delivery state of the disposition, but that doesn't seem incredibly helpful unless I can match it to a message.

Thanks for the quick response!
I'd like to match the response I get to a specific message that was sent. So if I'm sending multiple messages, I'd like to be able to know which message a particular disposition frame corresponds to. And, correct me if I'm wrong (perhaps I'm thinking about this wrong), right now the only thing I'd be able to do is count how many dispositions come back. I'm able to get the remote delivery state of the disposition, but that doesn't seem incredibly helpful unless I can match it to a message.

Hi Andrew,
I happened to be looking in a related area earlier and believe you are correct, it is not possible to access the deliveryId since the API doesnt expose that detail and it is only managed internally by the
transport+session (along with the dispositions themselves). What it is
you need the deliveryId for?

Hi Andrew,
I happened to be looking in a related area earlier and believe you are
correct, it is not possible to access the deliveryId since the API
doesnt expose that detail and it is only managed internally by the
transport+session (along with the dispositions themselves). What it is
you need the deliveryId for?
