Push Members Down
The Push Members Down refactoring helps clean up the class hierarchy by moving class members to a subclass. The members are then relocated into the direct subclasses only.
To push members down
- In the editor open a class, whose members you need to push down.
- On the main menu or on the context menu, choose Push Members Down dialog box displays the list of members to be pushed down. .
- In the Members to be pushed down area, select the members you want to move.
Note that the member at caret is already selected.
If pushing a member might cause problems, you will be notified with red highlighting. It means that, if the situation is unattended, an error will emerge after refactoring. CLion prompts you with a Problems Detected dialog, where you can opt to ignore or fix the problem.
- Preview and apply changes.
