Re: [paho-dev] Java client: per subscription message handling callbacks

Hi,

The Python client does this and checks every callback filter to see if it matches, and hence will deliver a single message to multiple callbacks if they overlap. It will deliver the message to the "global" callback if it does not match any of the filtered callbacks.

Cheers,

Roger

What is the proposal for deciding which subscription if the topic matches more than one subscription and the server only sends one message, or if it sends one per subscription?

I'm proposing to add per subscription message handling callbacks to the
Java client.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=466579

This will mean having to parse and match the incoming topics, as MQTT
does not send the subscription topic with each message, but the topic on
which the original message was published.  I have some simple code that
does that in the embedded C++ client however.

Any thoughts or comments welcome, here or in the bug....

Thanks
