I have an XML input stream which I want to unmarshall.
Let's say it looks like this:
<phone_book>
<person number="555-1212"... />
...
(about a million of these)
...
<person ... />
</phone_book>
However, I want to explicitly provide the top-level
object which corresponds to <phone_book>, rather than
simply put a class name in the mapping file.
I.e., what I want to do is have PhoneBook be an interface
and do something like this (fantasy code marked by ###):
PhoneBook pb = new SomePhoneBookImpl();
pb.setSomeAttr(...);
pb.loginToSomeDirectoryDB(...);
pb.doSomeOtherStuff(...);
Unmarshaller u = new Unmarshaller(myMappingFile);
### u.setRootObject(pb);
u.unmarshall(myPhoneBookInfoSource);
Is there any way to do this? The key point it that
it must be done early; i.e., I need to be able to
set up the PhoneBook object as I see fit before
the unmarshaller starts invoking setXXX/addXXX methods
on it to add the Person objects.
TIA,
