public static interface YLabel.UserDataHandler
This interface is used during YGF serialization to delegate the copying and serialization/deserialization of any user-defined data to. Registered implementations of this interface will be used to perform the actual serialization and deserialization of the user-defined data object. Additionally, implementations are responsible for creating appropriate copies of the user-defined data.
