Provided Methods

fn keyPathsForValuesAffectingValueForKey( key: &NSString, ) -> Retained<NSSet<NSString>>

Available on crate features NSSet and NSString only.

fn automaticallyNotifiesObserversForKey(key: &NSString) -> bool

Available on crate feature NSString only.

fn observationInfo(&self) -> *mut c_void
