Suppose the behaviour of class M is specified with the following state machine evt3 / a2 evt1 / a2 state1 exit a1 state2 entry a3 exit a4 >% state3 entry a4 evt4 a6 evt2 state5 entry a5 state4 exit a5 evt3 / a6 evt2 a. [5 marks] Using the (extended) state design pattern, what will be the structure of the class diagram and what would be the responsibilities of the different operations (shown in pseudo code) for realizing the desired behaviour? (Hint: see slide 155 from System Design) b. [5 marks] Suppose that an instance of class M has just been created and therefore is in state1 Assuming that the following sequence of events is received: evt1, evt3, evt2, represent in a sequence diagram the messages exchanged by the instances of the classes from the answer to 5.a.
