Smarter and Faster Introduce Parameter in Java

As a logical next step after inplace introduce variable refactoring we did in IntelliJ IDEA 10, version 10.5 will offer inplace introduce parameter.

Here is a brief overview of what we’re working on.

Once called, it will gently ask you to choose a method you want to add parameter to

Note, that you can introduce parameter in hierarchy by selecting the “Use super method of” option.

Then you’ll get a familiar template-like editor with a possibility to change parameter type and name. The refactoring settings you’ve got used to have in the dialog, are now available during template editing. You can make the parameter final, and generate method delegate, to remove unused parameters and replace field usages with getters. When multiple occurrences found you will be able to replace all of them or decide to replace only one right in place. No need to rerun the refactoring to see the results — they are already in the editor.

All method usages are already processed once you finish typing.

Just make sure you have inplace refactoring enabled in ‘IDE Settings | Editor | Enable in place refactorings‘.

The feature will be available in IntelliJ IDEA 10.5 EAP.

Watch our progress on inplace refactorings and let us know what you think!
