Transition rules connect the events generated by objects, and the states of these objects. Each rule consists of the starting state of the object, an event, and an ending state that the object will take after the event.

The table lists the transition rules from one object state to another. Each rule has the following properties:

1. Event – identifier of the event triggering the transition.
2. Transition from state – identifier of the object state before the event took place. If this field is left blank, the rule will apply to all starting states.
3. Transition to state – identifier of the resultant state of the object.
