Uses of Window in org.apache.flink.streaming.api.datastream

Classes in org.apache.flink.streaming.api.datastream with type parameters of type Window

Modifier and Type	Class and Description
class	AllWindowedStream<T,W extends Window> A AllWindowedStream represents a data stream where the stream of elements is split into windows based on a WindowAssigner.
static class	CoGroupedStreams.WithWindow<T1,T2,KEY,W extends Window> A co-group operation that has KeySelectors defined for both inputs as well as a WindowAssigner.
static class	JoinedStreams.WithWindow<T1,T2,KEY,W extends Window> A join operation that has KeySelectors defined for both inputs as well as a WindowAssigner.
class	WindowedStream<T,K,W extends Window> A WindowedStream represents a data stream where elements are grouped by key, and for each key, the stream of elements is split into windows based on a WindowAssigner.
