Class KryoRegistrationSerializerConfigSnapshot<T>

java.lang.Object

org.apache.flink.core.io.VersionedIOReadableWritable

org.apache.flink.api.common.typeutils.TypeSerializerConfigSnapshot

org.apache.flink.api.common.typeutils.GenericTypeSerializerConfigSnapshot<T>

org.apache.flink.api.java.typeutils.runtime.KryoRegistrationSerializerConfigSnapshot<T>

Type Parameters:

T - the data type that the Kryo serializer handles.

All Implemented Interfaces:

IOReadableWritable, Versioned

Direct Known Subclasses:

KryoSerializer.KryoSerializerConfigSnapshot, ValueSerializer.ValueSerializerConfigSnapshot

@Internal
public abstract class KryoRegistrationSerializerConfigSnapshot<T>
extends GenericTypeSerializerConfigSnapshot<T>

Configuration snapshot base class for serializers that use Kryo for serialization.

The configuration captures the order of Kryo serializer registrations, so that new Kryo serializers can determine how to reconfigure their registration order to retain backwards compatibility.
