# readability-convert-member-functions-to-static

Finds non-static member functions that can be made `static` because the functions don’t use `this`.

After applying modifications as suggested by the check, running the check again might find more opportunities to mark member functions `static`.

After making a member function `static`, you might want to run the check readability-static-accessed-through-instance to replace calls like `Instance.method()` by `Class::method()`.
