Change signature

Change a method or function signature

1. Click a method/function name that you want to refactor.

2. Press Ctrl+F6. Alternatively, select Refactor | Change Signature from the main menu or from the context menu.

3. In the Change Signature dialog, make the necessary changes to the method/function signature depending on your needs:

   • Change the method/function name. To change the name, edit the text in the Name field.

   • Manage the method/function parameters. To configure the parameters, use the table and the buttons in the Parameters area:

     • To add a new parameter, click and specify the properties of the new parameter in the corresponding table row.

     • To remove a parameter, select any row and click .

     • To reorder the parameters, use the Up () and Down () icons.

     • To declare multiple variables of the same type, select the Reuse types checkbox. Variables of the same type must be declared one after another. So, instead of firstName string, lastName string, age int, id int, you will get firstName, lastName string, age, id int.

     • To change the name or the default value of a parameter, make the necessary updates in the table of parameters (in the fields Name and Default value respectively).

4. Click Refactor.
