    None of these methods will work after the server restarts. The only way to identify an entity is to edit its NBT tag, or to use EntityMetadata.

    You can't because it doesn't exist. It only gets instantiated when the entity is being saved. To edit it, extend that entity's class and implement that method in your own class's saveNBT function.

    Actually $entity->namedtag is public and contains the NBT data. So you can modify that directly. However, the saveNBT method will modify the NBT data.

    The proper OOP way of doing this is to override saveNBT method.

    Just look at PocketMine source code. Most uses are in the Entity class.
