Method Detail

void start()

Starts the state machine and returns.

waitForStop

States waitForStop()
            throws java.lang.InterruptedException

Waits for the state machine to stop executing.

the final state in which the machine stopped

Throws:

java.lang.InterruptedException - if the waiting thread is interrupted

stop

void stop()

Force an early termination of the state machine, in response to user submitting a kill via API or ctrl-c. Notice: - State actions are not interrupted. Only after the one currently executing is completed the stop signal is processed (TODO: make long-running actions, such as setup, interruptable). - Some actions are still performed before the program exits. For example publish the updated job status server-side. Refer to the StateMachineAutoConfiguration for details.
