Hi ha tipus especials d' estat: Inici i final. Són especials en que no hi ha cap esdeveniment que pugui fer que l' objecte retorni al seu estat d' inici, de la mateixa manera que no hi ha cap esdeveniment que pugui fer que un objecte surti del seu estat de final una vegada que l' ha assolit.
There are two special types of States: Start and End. They are special in that there is no event that can cause an Object to return to its Start state, in the same way as there is no event that can possible take an Object out of its End state once it has reached it.
