abstract class RichAllWindowFunction[IN, OUT, W <: Window] extends AbstractRichFunction with AllWindowFunction[IN, OUT, W]

Rich variant of the org.apache.flink.streaming.api.scala.function.AllWindowFunction.

As a org.apache.flink.api.common.functions.RichFunction, it gives access to the org.apache.flink.api.common.functions.RuntimeContext and provides setup and tear-down methods.

IN

The type of the input value.

OUT

The type of the output value.

W

The type of Window that this window function can be applied on.
