| componentOrGameObject | 要检查的对象。必须是组件或游戏对象。 |
bool 如果该对象是无法编辑的预制件的一部分，则返回 true。
该对象是无法编辑的预制件的一部分？
对于预制件资源上的对象，将检查资源本身。对于预制件实例上的对象，将检查其相应的资源。
永久预制件的示例为模型预制件和只读文件夹中的预制件。
For Prefab contents loaded in Prefab Mode, this method will not check the Prefab Asset the loaded contents are loaded from, since these Prefab contents are loaded into a preview scene and are not part of an Asset while being edited in Prefab Mode. This means that for Prefab contents in Prefab Mode, the method will return true for instances of immutable Prefabs, but not for GameObjects or components that are not part of a Prefab instance.
