Inline Class
Problem
A class does almost nothing and isn't responsible for anything, and no additional responsibilities are planned for it.
Solution
Move all features from the class to another one.
Why Refactor
- Often this technique is needed after the features of one class are "transplanted" to other classes, leaving that class with little to do.
Benefits
- Eliminating needless classes frees up operating memory on the computer—and bandwidth in your head.
How to Refactor
-
In the recipient class, create the public fields and methods present in the donor class. Methods should refer to the equivalent methods of the donor class.
-
Replace all references to the donor class with references to the fields and methods of the recipient class.
-
Now test the program and make sure that no errors have been added. If tests show that everything is working A-OK, start using Move Method and Move Field to completely transplant all functionality to the recipient class from the original one. Continue doing so until the original class is completely empty.
-
Delete the original class.
