Method Details

newInstance

FSM newInstance(Object uuid,
 C context,
 D data,
 BiConsumer<S,Object> onUnhandledEvent,
 TransitionListener<S> transitionListener)

Create a new FSM based off of this Definition and assign a unique UUID to this state machine. The FSM itself doesn't actually use the UUID other but may be important for the applications who actually are using this FSM. Also pass in a handler for any events that doesn't match the FSM. This allows you to take action if there are any events that has been missed when creating the FSM. A common best practice is to at the very least log on WARN so your systems can alert you to the fact that your FSM is missing a transition.

Parameters:

uuid -

context -

data -

onUnhandledEvent -

Returns:

FSM newInstance(Object uuid,
 C context,
 D data)

Parameters:

Returns:
