8  * only (each transition must have a unique identity).
9  *
10  * @param event [`Event`][Event] - triggering event for this transition.
11  * @param statePath a list of states for this transition.
12  *                  First item is a starting state for the transition.
13  *                  Must have at least two items. Must not have repeating items in a row.
14  *
15  * @throws [IllegalArgumentException] if statePath has less than 2 items OR has repeating items in a row
16  *
17  * @param [Event] event parameter of enum type.
18  * @param [State] state parameter of enum type.
