1 00:00:01,000 --> 00:00:06,850 The structural barriers provide a common solution to common issues related to object structures and 2 00:00:06,850 --> 00:00:13,210 features of those factors is the fact that they rely on old concepts like inheritance and polymorphism 3 00:00:13,480 --> 00:00:15,980 to allow multiple classes to work synergistically. 4 00:00:16,840 --> 00:00:23,110 Some of the structural barriers are the following adopter bridge filter, composite decorator, facade 5 00:00:23,110 --> 00:00:26,510 flyweight and Foxe in the following videos. 6 00:00:26,530 --> 00:00:32,830 I'm going to explain the structure better in detail, so I invite you to join me in the next video where 7 00:00:32,830 --> 00:00:35,500 we are going to discuss about Dr Pattern.
