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. |
