Refactoring with preview

1. Activate a refactoring command. For example, rename a type by selecting it in the Outline view and choosing Refactor > Rename from its pop-up menu.

2. The Refactoring Parameters page prompts you for information necessary for the action. For example, the Rename Type Refactoring dialog asks you for the new name for the selected type.

3. Provide the necessary data on the parameters page, and then click Preview.

4. If problems more severe than the default level set in the Refactoring Preferences page (Window > Preferences > Java > Refactoring) are anticipated, then the problems page comes to the front to display anticipated errors.

   • If a Stop problem was anticipated, then only the Back and Cancel buttons are enabled, and you are prevented from carrying out the refactoring. If the problems are related to data provided on the parameters page, click Back and attempt to remedy the problem. Otherwise, click Cancel to close the dialog.

   • If other kinds of problems were anticipated, you can click Continue to acknowledge the problems and move on to the preview page.

   The Refactoring Preview page opens.

5. Click OK to execute the refactoring and close the dialog.
