XMLEncoder 和 PersistenceDelegate
我正在尝试使用 XMLEncoder 将对象图（在我的例子中为树）写入文件。然而，其中包含的一个类实际上并不是 Java bean，而且我不太喜欢公开其内部内容。它的访问方式更像是一个列表，并且具有适当的 add/remove 方法。
我已经编写了一个自定义的 PersistenceDelegate 来处理这个问题。但是，似乎我必须手动将 PersistenceDelegate 添加到 XMLEncoder 实例。
有没有办法让 XMLEncoder 自行获取它，或者每当我使用编码器编写可能包含所述类的图形时，我真的需要添加它吗？
I'm trying to use XMLEncoder to write an object graph (tree in my case) to a file. However, one class contained in it is not actually a Java bean and I don't particularly like making its guts publicly accessible. It's accessed more like a list and has appropriate add/remove methods.
I've already written a custom PersistenceDelegate to deal with that. However, it seems that I have to add the PersistenceDelegate to the XMLEncoder instance manually.
Is there any way for XMLEncoder to pick it up on its own or do I really need to add it whenever I use an encoder to write a graph that may contain said class?

深入研究我们的代码库，我发现了一个
XMLEncodeFactory类，它允许为某些类注册PersistenceDelegates并处理使用这些委托创建XMLEncoder实例。放。代码本身非常简单，但我认为 Java 已经提供了这种功能。有人告诉我这是在与
XMLEncoder类的原始开发人员交谈后创建的，显然没有更好的替代方案。Digging through our codebase I came across a
XMLEncodeFactoryclass which allows one to registerPersistenceDelegatesfor certain classes and handles creatingXMLEncoderinstances with those delegates pre-set. The code itself is very straightforward but I would have thought such a capability would be already offered by Java.I was told this was created after conversation with the original developers of the
XMLEncoderclass and there apparently isn't a nicer alternative.
