类 ListViewSerializer<T>

java.lang.Object

org.apache.flink.api.common.typeutils.TypeSerializer<ListView<T>>

org.apache.flink.table.dataview.ListViewSerializer<T>

类型参数:

T - The type of element in the list.

所有已实现的接口:

Serializable, org.apache.flink.api.common.typeutils.LegacySerializerSnapshotTransformer<ListView<T>>

@Internal
public class ListViewSerializer<T>
extends org.apache.flink.api.common.typeutils.TypeSerializer<ListView<T>>
implements org.apache.flink.api.common.typeutils.LegacySerializerSnapshotTransformer<ListView<T>>

A serializer for [[ListView]]. The serializer relies on an element serializer for the serialization of the list's elements.

The serialization format for the list is as follows: four bytes for the length of the list, followed by the serialized representation of each element.

serialize

public void serialize(ListView<T> record,
                      org.apache.flink.core.memory.DataOutputView target)
               throws IOException

指定者:

serialize 在类中 org.apache.flink.api.common.typeutils.TypeSerializer<ListView<T>>

抛出:

public ListView<T> deserialize(ListView<T> reuse,
                               org.apache.flink.core.memory.DataInputView source)
                        throws IOException

指定者:

deserialize 在类中 org.apache.flink.api.common.typeutils.TypeSerializer<ListView<T>>

抛出:

equals

public boolean equals(Object obj)

指定者:

equals 在类中 org.apache.flink.api.common.typeutils.TypeSerializer<ListView<T>>

hashCode

public int hashCode()

指定者:

hashCode 在类中 org.apache.flink.api.common.typeutils.TypeSerializer<ListView<T>>

transformLegacySerializerSnapshot

public <U> org.apache.flink.api.common.typeutils.TypeSerializerSnapshot<ListView<T>> transformLegacySerializerSnapshot(org.apache.flink.api.common.typeutils.TypeSerializerSnapshot<U> legacySnapshot)

We need to override this as a LegacySerializerSnapshotTransformer because in Flink 1.6.x and below, this serializer was incorrectly returning directly the snapshot of the nested list serializer as its own snapshot.

This method transforms the incorrect list serializer snapshot to be a proper ListViewSerializerSnapshot.

指定者:

transformLegacySerializerSnapshot 在接口中 org.apache.flink.api.common.typeutils.LegacySerializerSnapshotTransformer<ListView<T>>
