Replace Constructor with Factory Method refactoring
This refactoring helps implement the factory method pattern for an existing class. If you opt to create the factory method in the same class, the refactoring makes the selected constructor private and encapsulates it into a static method that returns a new instance of the class. You can als choose to create the factory method in any other class. In this case, the constructor stays public, you can change its access modifier later, if necessary.
If there are any usages of the constructor, they are replaced with factory method calls.
In the example below, we use the refactoring to add the factory method in the same class:
To replace a constructor with a factory method
In the editor, place the caret at a constructor or choose a constructor in the Structure window.
- Do one of the following:
Press Ctrl+Shift+R and then choose Replace Constructor with Factory Method
Choosein the main menu.
Specify a name for the factory method or accept the suggested name.
By default, the refactoring creates factory method in the same class. If you want to create the factory method in another class, specify the fully qualified name of the class.
To apply the refactoring, click Next.
- If no conflicts are found, JetBrains Rider performs the refactoring immediately. Otherwise, it prompts you to resolve conflicts.
