> Right now, when using a {{WrappingFunction}}, as happens for 
> {{WindowFunction}} and also for some functions in the Scala API then using 
> custom interfaces is not possible. These custom interfaces are, for example, 
> the checkpointing functions such as {{ListCheckpointed}} and 
> {{CheckpointedFunction}}.
> We should teach {{AbstractUdfStreamOperator}} about {{WrapingFunction}} so 
> that it can correctly handle the case where wrapped user functions implement 
> on of these interfaces.
> Also, in the Scala API we have some custom functions that mimic 
> {{WrappingFunction}} behaviour. These should be moved to use 
> {{WrappingFunction}}, if possible.
