java序列化CachedRowSet

Question

所以我已经理解了什么是CachedRowSet。它主要保存数据，而其他行集/结果集每次都需要连接和检索数据。因为它不需要连接，所以是可序列化的，我引用了CachedRowSet的JavaSE8文档

A CachedRowSet object is a container for rows of data that caches its rows in memory, which makes it possible to operate without always being connected to its data source. Further, it is a JavaBeans™ component and is scrollable, updatable, and serializable.

我已经尽我所能搜索了文档，如果它是可序列化的，那么它必须直接或间接地在层次结构的更高层实现可序列化接口。我看不到这一点，所以我对它在没有可序列化实现的情况下如何可序列化感到困惑
