Classes in org.apache.flink.streaming.api.functions.windowing that implement WindowFunction

Modifier and Type	Class	Description
class	AggregateApplyWindowFunction<K,W extends Window,T,ACC,V,R>	A WindowFunction that composes an AggregateFunction and WindowFunction.
class	PassThroughWindowFunction<K,W extends Window,T>	A WindowFunction that just emits each input element.
class	ReduceApplyWindowFunction<K,W extends Window,T,R>	Internal WindowFunction that is used for implementing a fold on a window configuration that only allows WindowFunction and cannot directly execute a ReduceFunction.
