Change Signature Dialog

Refactor | Change Signature


The Change Signature refactoring combines several different modifications that can be applied to a function, method, or a method specification. You can use this refactoring for the following purposes:

  • To change the method name.

  • To add new parameters and remove the existing ones.

  • To assign default values to new non-variadic parameters.

  • To reorder parameters.

When changing a method signature, GoLand searches for all usages of the method and updates all the calls, implementations, and override replacements of the method that can be safely modified to reflect the change. When you refactor a method specification, you will see a notification dialog where you can select to update all implementations as well.
