Cancelling a running AO query

[Igor Sereda [ALM Works]]

Is there a way to cancel a running AO query?

There are two cases:

1. Synchronous cancelling from inside ActiveObjects.stream() and a callback. I don't see a good way, but probably just throwing an unchecked exception would do the trick.
2. More importantly, asynchronous cancelling from another thread, especially at the stage when no rows have been served yet.

This functionality is required to correctly implement Activity Streams provider that observes the timeout. I would be very glad to hear if someone has solved this yet. We're keen to go around the API with reflection etc. to get what we need.

Thanks!
Igor

Your best options are to throw an unchecked exception for use case 1 and to just interupt the thread for use case 2. If the JDBC connection is waiting it should terminate on an interrupt. Reflection isn't going to help you in this situation and is strongly discouraged.
