+00:00:00,150 --> 00:00:03,825
+This new refactoring called inline class is the reverse of the extract class
+
+2
+00:00:03,825 --> 00:00:06,700
+refactoring. And know that this is kind of a general situation in the
+
+3
+00:00:06,700 --> 00:00:09,500
+sense that it is often the case that the refactoring also has a
+
+4
+00:00:09,500 --> 00:00:11,480
+reverse refactoring that does exactly the
+
+5
+00:00:11,480 --> 00:00:13,202
+opposite. So basically, un-dos, in a sense,
+
+6
+00:00:13,202 --> 00:00:16,830
+the operation of the other refactoring. In this case, the motivation for the
+
+7
+00:00:16,830 --> 00:00:19,760
+refactoring is that during system evolution, we might end up with one or
+
+8
+00:00:19,760 --> 00:00:22,530
+more classes that do not do much. In this case what you want
+
+9
+00:00:22,530 --> 00:00:25,350
+to do is to take the class that is not doing that much and
+
+10
+00:00:25,350 --> 00:00:28,740
+move its features into another class. And then delete the original class.
+
+11
+00:00:28,740 --> 00:00:31,010
+So lets use an example similar to the one we've used for
+
+12
+00:00:31,010 --> 00:00:34,000
+the previous refactoring to illustrate how this works. Here we have in
+
+13
+00:00:34,000 --> 00:00:37,750
+this case, two classes, person and office. And the person class is
+
+14
+00:00:37,750 --> 00:00:40,720
+using the office class, but this latter class, the office class, only
+
+15
+00:00:40,720 --> 00:00:44,000
+contains a phone number. So it doesn't really do that much. What
+
+16
+00:00:44,000 --> 00:00:47,020
+we can do is therefore to fold the office class into the
+
+17
+00:00:47,020 --> 00:00:50,470
+person class, by simply moving its only field into the class. And so
+
+18
+00:00:50,470 --> 00:00:53,260
+the result will be this person class that also contains the information
+
+19
+00:00:53,260 --> 00:00:56,600
+about the office number, and overall a simpler design for the code.
