Hi Jarl
That's what I thought... However the context I am requesting this feature is VERY controlled. It's in a unit test. Everything is in one thread, I wait for the scheduler to process all events, and then I want probe the state and verify correct state. It may sound like test of the statechartlibrary itself. It's not; I am testing that I have correctly defined my statemachine.
So is there a way to come from sc::fifo_scheduler<>::processor_handle to AsyncMachine (which inherits sc:asynchronous_state_machine)?
No, for the same reasons. A sc:asynchronous_state_machine<> subtype is serviced by the fifo_scheduler thread. Directly accessing it from a different thread would again open the door to race-conditions or dead-locks.
Yes, under normal conditions (hostile production environment). But not in test envs.
The proper way to query an asynchronous state machine is by sending it a special event carrying a boost::function object.
Interesting, that sounds like a feasible solution for the test. The function could probably be the assertion itself. Thanks for the answer, I might have a look at it. Jarl
