Interface Summary

Interface	Description
AllWindowFunction<IN,OUT,W extends Window>	Base interface for functions that are evaluated over non-keyed windows.
WindowFunction<IN,OUT,KEY,W extends Window>	Base interface for functions that are evaluated over keyed (grouped) windows.

Class Summary

Class	Description
AggregateApplyAllWindowFunction<W extends Window,T,ACC,V,R>	A AllWindowFunction that composes an AggregateFunction and AllWindowFunction.
AggregateApplyWindowFunction<K,W extends Window,T,ACC,V,R>	A WindowFunction that composes an AggregateFunction and WindowFunction.
InternalProcessApplyAllWindowContext<IN,OUT,W extends Window>	Internal reusable context wrapper.
InternalProcessApplyWindowContext<IN,OUT,KEY,W extends Window>	Internal reusable context wrapper.
PassThroughAllWindowFunction<W extends Window,T>	A AllWindowFunction that just emits each input element.
PassThroughWindowFunction<K,W extends Window,T>	A WindowFunction that just emits each input element.
ProcessAllWindowFunction<IN,OUT,W extends Window>	Base abstract class for functions that are evaluated over non-keyed windows using a context for retrieving extra information.
ProcessWindowFunction<IN,OUT,KEY,W extends Window>	Base abstract class for functions that are evaluated over keyed (grouped) windows using a context for retrieving extra information.
ReduceApplyAllWindowFunction<W extends Window,T,R>	Internal AllWindowFunction that is used for implementing a fold on a window configuration that only allows AllWindowFunction and cannot directly execute a ReduceFunction.
