org.apache.flink.streaming.runtime.streamrecord

类 StreamElementSerializer<T>

java.lang.Object

org.apache.flink.api.common.typeutils.TypeSerializer<StreamElement>

org.apache.flink.streaming.runtime.streamrecord.StreamElementSerializer<T>

类型参数:

T - The type of value in the StreamRecord

所有已实现的接口:

Serializable

@Internal
public final class StreamElementSerializer<T>
extends org.apache.flink.api.common.typeutils.TypeSerializer<StreamElement>

Serializer for StreamRecord, Watermark, LatencyMarker, and StreamStatus.

This does not behave like a normal TypeSerializer, instead, this is only used at the stream task/operator level for transmitting StreamRecords and Watermarks.
