final class ScalaWindowFunctionWrapper[IN, OUT, KEY, W <: Window] extends WrappingFunction[WindowFunction[IN, OUT, KEY, W]] with functions.windowing.WindowFunction[IN, OUT, KEY, W] with RichFunction

A wrapper function that exposes a Scala WindowFunction as a JavaWindow function.

The Scala and Java Window functions differ in their type of "Iterable":
