Its heart is a series of small behavior preserving transformations. public Circle(Color c) But then you find that there's no single .cpp file that includes the base class' definition; there are other files that include it, but they also include subclasses, which still haven't been refactored and still do not compile. InitPainter(myColor); }. Encapsulate Field. private Color myColor; The class that you merge in is removed, its members are moved to the class where the merged class is used, and all usages of the merged class are updated accordingly.

Consider applying “inline class” refactoring [7] to merge the class with another class. { Learn how to recognize "code smells" that may indicate the need for refactoring and how to fix them with specific techniques and patterns. 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. An example of refactoring from a real (flawed) code base. class Person { get officeAreaCode() {return this._officeAreaCode;} get officeNumber() {return this._officeNumber;} }, class Circle } myPainter = new Painter(c); This refactoring allows you to merge one class into another class. Is there a sequence of IntelliJ automated refactoring's that will get rid of the superfluous class Foo?

For details specific to other languages, see corresponding topics in the ReSharper by Language section. Another important result is untangling of class associations, which … Eliminates smell. The refactoring creates a declaration in the header, and moves the implementation near those of other methods in the same class. ReSharper | Refactor | Inline | Inline… Control+Alt+N ReSharper_InlineVariable. The one thing to watch out for is that the simple method you're intending to get rid of is polymorphic, in that it may have been written in a very simple format in the super class just so it could be overwritten in a subclass. Refactoring is usually motivated by noticing a code smell. Choose ReSharper | Refactor | Inline | Inline… in the main menu. private void InitPainter(Color color) This refactoring is often initiated after other refactorings that place implementations in header files for inline execution, e.g. Because it's in the nature of classes to …grow, they start to take on more than their original intention.
