Re: [Simple-support] Deserializing polymorphic types.

[Niall G. - Y. <Nia...@yi...>]

It would look something like this, check out the test cases I have done this very thing several times there.

class MyStrategy extends AnnotationStrategy{

   @Override
   read(InputNode n, …) {
      String className = n.getAttribute(“class”).getValue();

      if(className.equals(“x”)) {
         className = “y”;
      }
      // etc…
   }
}

Niall, thank you for response. To be more specific, I create serializer with AnnotationStrategy:

Strategy strategy = new AnnotationStrategy();
mSerializer = new Persister(strategy);

Than, I am using it to read slide:
mSerializer.read(Slide.class, bis);

Class Slide has list of elements of polimorphic type:
@ElementList(name = "mList")
private PrsArrayList<Element> mElementList = null;
"Element" is base class of the things which are serialized.

Could you please provide some pseudo code how to achieve the goal?? How to do this mapping? Thank you!

Ya, you can use a Strategy or a Visitor to do this. Another alternative is to open a text editor and do a search an replace on the XML.

 I am using SimpleXML
 to serialize classes. I am serializing polymorphic types as
 well.
 Due to this I came across a problem. I would like
 to do code refactoring and move some classes between
 packages. After I did it old XML files created before
 refactoring cannot be read. Simple framwork is throwing
 exception that class is not found. In XML full path to class
 is stored so after I changed class package class cannot not
 be found. What is the solution to this problem? Is there any
 way to apply kind of mapping between old and new class
 location???
 Thank you,
 BR, M
