+/**
+ * Abstract class implementing IWifiManager with stub methods throwing runtime exceptions.
+ *
+ * This class is meant to be extended by real implementations of IWifiManager in order to facilitate
+ * cross-repo changes to WiFi internal APIs, including the introduction of new APIs, the removal of
+ * deprecated APIs, or the migration of existing API signatures.
+ *
+ * When an existing API is scheduled for removal, it can be removed from IWifiManager.aidl
+ * immediately and marked as @Deprecated first in this class. Children inheriting this class are
+ * then given a short grace period to update themselves before the @Deprecated stub is removed for
+ * good. If the API scheduled for removal has a replacement or an overload (signature change),
+ * these should be introduced before the stub is removed to allow children to migrate.
