RichWindowFunction

abstract class RichWindowFunction[IN, OUT, KEY, W <: Window] extends AbstractRichFunction with WindowFunction[IN, OUT, KEY, W]

Rich variant of the org.apache.flink.api.function.WindowFunction.

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.

KEY

The type of the key.

W

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