A dependency, + +2 +00:00:03,040 --> 00:00:06,720 +as we said, expresses the relationship between a supplier + +3 +00:00:06,720 --> 00:00:09,290 +and a client that relies on it. There is + +4 +00:00:09,290 --> 00:00:12,490 +a dependency because changes in the supplier can affect the + +5 +00:00:12,490 --> 00:00:14,770 +client. Here in this example I am showing that + +6 +00:00:14,770 --> 00:00:18,510 +a dependency example involving the registration manager and the + +7 +00:00:18,510 --> 00:00:21,590 +scheduling algorithm. As you can see the, the dependency + +8 +00:00:21,590 --> 00:00:25,710 +is indicated with a dashed line pointing from the client + +9 +00:00:25,710 --> 00:00:28,520 +to the supplier. And here it's pretty clear why + +10 +00:00:28,520 --> 00:00:31,820 +the RegistrationManager is dependent on the Scheduling Algorithm. It's + +11 +00:00:31,820 --> 00:00:35,710 +because the RegistrationManager uses this Scheduling Algorithm. And therefore, + +12 +00:00:35,710 --> 00:00:39,130 +if the Scheduling Algorithm changes, the RegistrationManager might be + +13 +00:00:39,130 --> 00:00:42,210 +affected by that change. Another less obvious example is + +14 +00:00:42,210 --> 00:00:45,600 +the dependency between the Registration Manager and the Student. + +15 +00:00:45,600 --> 00:00:48,040 +In this case, because the Registration Manager gets a + +16 +00:00:48,040 --> 00:00:51,620 +Student object as a parameter here there is a dependency + +17 +00:00:51,620 --> 00:00:55,740 +between the two. Again, if the Student class were to change the Registration + +18 +00:00:55,740 --> 00:01:00,270 +Manager might be affected because it's relying on the Student for it's behavior. |
