方法详细资料

upperBoundExclusive

@PublicEvolving
public KeyedStream.IntervalJoined<IN1,IN2,KEY> upperBoundExclusive()

Set the upper bound to be exclusive.

lowerBoundExclusive

@PublicEvolving
public KeyedStream.IntervalJoined<IN1,IN2,KEY> lowerBoundExclusive()

Set the lower bound to be exclusive.

process

@PublicEvolving
public <OUT> SingleOutputStreamOperator<OUT> process(ProcessJoinFunction<IN1,IN2,OUT> processJoinFunction)

Completes the join operation with the given user function that is executed for each joined pair of elements.

类型参数:

OUT - The output type.

参数:

processJoinFunction - The user-defined process join function.

返回:

The transformed DataStream.

process

@PublicEvolving
public <OUT> SingleOutputStreamOperator<OUT> process(ProcessJoinFunction<IN1,IN2,OUT> processJoinFunction,
                                                                     org.apache.flink.api.common.typeinfo.TypeInformation<OUT> outputType)

Completes the join operation with the given user function that is executed for each joined pair of elements. This methods allows for passing explicit type information for the output type.
