Example:
import foo.Foo.Bar;
class Foo {
class Bar {}
}
class Baz {
void f(Bar bar) {}
}
After the quick-fix is applied:
class Foo {
class Bar {}
}
class Baz {
void f(Foo.Bar bar) {}
}
Use the inspection settings to ignore references to inner classes within the same class, which therefore do not require an import.
