ScalaWindowFunctionWrapper

org.apache.flinkx.api.function.util.ScalaWindowFunctionWrapper
final class ScalaWindowFunctionWrapper[IN, OUT, KEY, W <: Window](func: WindowFunction[IN, OUT, KEY, W]) extends WrappingFunction[WindowFunction[IN, OUT, KEY, W]], WindowFunction[IN, OUT, KEY, W], 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":

  • Scala WindowFunction: scala.Iterable
  • Java WindowFunction: java.lang.Iterable
