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

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

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

Type parameters

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.

trait StatefulFunction[I, O, S] extends RichFunction

Trait implementing the functionality necessary to apply stateful functions in RichFunctions without exposing the OperatorStates to the user. The user should call the applyWithState method in his own RichFunction implementation.
