detachFromLifecycle |
Detaches the given ListenerHolder open fun detachFromLifecycle(key: Any, listenerHolder: ListenerHolder<*>): ListenerHolder<*>?
Detaches the ListenerHolder attached under key open fun detachFromLifecycle(key: Any): ListenerHolder<*>? |
isAttached |
Returns true if the given listenerHolder is attached with the given key open fun isAttached(key: Any, listenerHolder: ListenerHolder<*>): Boolean |
