Method Summary

Modifier and Type	Method and Description
StreamCrossOperator.CrossWindow<I1,I2>	every(long length) Defines the slide interval for this temporal operator
StreamCrossOperator.CrossWindow<I1,I2>	every(long length, TimeUnit timeUnit) Defines the slide interval for this temporal operator
<R> SingleOutputStreamOperator<R,?>	with(org.apache.flink.api.common.functions.CrossFunction<I1,I2,R> function) Finalizes a temporal Cross transformation by applying a CrossFunction to each pair of crossed elements. Each CrossFunction call returns exactly one element.

with

public <R> SingleOutputStreamOperator<R,?> with(org.apache.flink.api.common.functions.CrossFunction<I1,I2,R> function)

Finalizes a temporal Cross transformation by applying a CrossFunction to each pair of crossed elements.
Each CrossFunction call returns exactly one element.

Parameters:

function - The CrossFunction that is called for each pair of crossed elements.

Returns:
