pub fn remove_meta(&mut self, name: impl AsArg<StringName>)

pub fn get_meta(&self, name: impl AsArg<StringName>) -> Variant

To set the default parameters, use Self::get_meta_ex and its builder methods. See the book for detailed usage instructions.

pub fn get_meta_ex<'a>( &'a self, name: impl AsArg<StringName> + 'a, ) -> ExGetMeta<'a>

pub fn has_meta(&self, name: impl AsArg<StringName>) -> bool

pub fn get_meta_list(&self) -> Array<StringName>

pub fn get_translation_domain(&self) -> StringName

pub fn set_translation_domain(&mut self, domain: impl AsArg<StringName>)

pub fn is_queued_for_deletion(&self) -> bool

pub fn cancel_free(&mut self)

pub fn notify(&mut self, what: ObjectNotification)

⚠️ Sends a Godot notification to all classes inherited by the object.

Triggers calls to on_notification(), and depending on the notification, also to Godot’s lifecycle callbacks such as ready().

Starts from the highest ancestor (the Object class) and goes down the hierarchy. See also Godot docs for Object::notification().

§Panics

If you call this method on a user-defined object while holding a GdRef or GdMut guard on the instance, you will encounter a panic. The reason is that the receiving virtual method on_notification() acquires a GdMut lock dynamically, which must be exclusive.

pub fn notify_reversed(&mut self, what: ObjectNotification)

⚠️ Like Self::notify(), but starts at the most-derived class and goes up the hierarchy.

See docs of that method, including the panics.
