public interface UserDataHolder
Allows storing custom user data within a model object. This might be preferred to an explicit Map with model objects as keys and custom data in values because this allows the data to be garbage-collected together with the values.

If you need to implement this interface, extend UserDataHolderBase or delegate to its instance instead of writing your own implementation.
