Extract Module

The Extract Module refactoring allows you to extract certain members from a selected class into a separate module.

To extract a module:

  1. Place a caret at a class name or any place within a class.

  2. Select Refactor | Extract | Module... on the main menu.

  3. In the Extract Module dialog, specify the module name, a directory where it should be placed, and select members to be added:
