已过时。

this snapshot class is no longer in use, and is maintained only for backwards compatibility. It is fully replaced by ScalaOptionSerializerSnapshot.

@Deprecated
public final class ScalaOptionSerializerConfigSnapshot<E>
extends org.apache.flink.api.common.typeutils.CompositeTypeSerializerConfigSnapshot<scala.Option<E>>

A TypeSerializerConfigSnapshot for the Scala OptionSerializer.

This configuration snapshot class is implemented in Java because Scala does not allow calling different base class constructors from subclasses, while we need that for the default empty constructor.
