Reports functions that override abstract members but do not have an override modifier.
Scala does not require a developer to use override
on methods that implement abstract members.
Nonetheless, it is a good idea to mark such methods with override
to be notified
by the compiler when the override relationship gets broken (by a subsequent refactoring, for example).
Example:
trait Base {
def fun(): Int
}
class Impl extends Base {
def fun(): Int = 42
}
After the quick-fix is applied:
trait Base {
def fun(): Int
}
class Impl extends Base {
override def fun(): Int = 42
}
