类 BatchTimestampsAndWatermarks<T>

java.lang.Object

org.apache.flink.streaming.api.operators.source.BatchTimestampsAndWatermarks<T>

类型参数:

T - The type of the emitted records.

所有已实现的接口:

TimestampsAndWatermarks<T>

@Internal
public class BatchTimestampsAndWatermarks<T>
extends Object
implements TimestampsAndWatermarks<T>

An implementation of TimestampsAndWatermarks to be used during batch execution of a program. Batch execution has no watermarks, so all watermark related operations in this implementation are no-ops.

构造器概要

构造器和说明
BatchTimestampsAndWatermarks(org.apache.flink.api.common.eventtime.TimestampAssigner<T> timestamps) Creates a new BatchTimestampsAndWatermarks with the given TimestampAssigner.

方法概要

限定符和类型	方法和说明
org.apache.flink.api.connector.source.ReaderOutput<T>	createMainOutput(PushingAsyncDataInput.DataOutput<T> output) Creates the ReaderOutput for the source reader, than internally runs the timestamp extraction and watermark generation.
void	startPeriodicWatermarkEmits() Starts emitting periodic watermarks, if this implementation produces watermarks, and if periodic watermarks are configured.
void	stopPeriodicWatermarkEmits() Stops emitting periodic watermarks.

Creates a new BatchTimestampsAndWatermarks with the given TimestampAssigner.

方法详细资料

createMainOutput

public org.apache.flink.api.connector.source.ReaderOutput<T> createMainOutput(PushingAsyncDataInput.DataOutput<T> output)

从接口复制的说明: TimestampsAndWatermarks

Creates the ReaderOutput for the source reader, than internally runs the timestamp extraction and watermark generation.

指定者:

createMainOutput 在接口中 TimestampsAndWatermarks<T>

startPeriodicWatermarkEmits

public void startPeriodicWatermarkEmits()

从接口复制的说明: TimestampsAndWatermarks

Starts emitting periodic watermarks, if this implementation produces watermarks, and if periodic watermarks are configured.

Periodic watermarks are produced by periodically calling the WatermarkGenerator.onPeriodicEmit(WatermarkOutput) method of the underlying Watermark Generators.

指定者:

startPeriodicWatermarkEmits 在接口中 TimestampsAndWatermarks<T>

stopPeriodicWatermarkEmits

public void stopPeriodicWatermarkEmits()

从接口复制的说明: TimestampsAndWatermarks

Stops emitting periodic watermarks.

指定者:

stopPeriodicWatermarkEmits 在接口中 TimestampsAndWatermarks<T>
