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. |
