XMLEncoder and PersistenceDelegate
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开发者_Go百科 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?
Digging through our codebase I came across a XMLEncodeFactory
class which allows one to register PersistenceDelegates
for certain classes and handles creating XMLEncoder
instances 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 XMLEncoder
class and there apparently isn't a nicer alternative.
