Class TraversableSerializerSnapshot<T extends scala.collection.TraversableOnce<E>,E>

java.lang.Object

org.apache.flink.api.common.typeutils.CompositeTypeSerializerSnapshot<T,org.apache.flink.api.scala.typeutils.TraversableSerializer<T,E>>

All Implemented Interfaces:

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

public class TraversableSerializerSnapshot<T extends scala.collection.TraversableOnce<E>,E>
extends org.apache.flink.api.common.typeutils.CompositeTypeSerializerSnapshot<T,org.apache.flink.api.scala.typeutils.TraversableSerializer<T,E>>

A TypeSerializerSnapshot for the Scala TraversableSerializer.

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.
