Change Signature dialog
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 to:
change the method name
add, remove, and reorder parameters
assign default values to new non-variadic 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.
