How do I specify the graffito jcr mapping for classes that extend ArrayList

[rajab57]

Example

import java.util.ArrayList;
import java.util.ListIterator;

public class MainClass {
   private ElementsList elements;

}

public class ElementsList extends ArrayList<Elements>  {
  private static final long serialVersionUID = 1L;

}


public class Element {
   private String name ;
   private String id ;

}

The jcr mapping tools has been moved into the Jackrabbit project (
http://jackrabbit.apache.org). I advise you to use the Jackrabbit mailing
list.

FYI, ArrayList are supportedd by default.

If you want to support your own collection/map class :
1/ your collection/map class have to implement the ManagableCollection
interface.
2/ You have to specify the collection class name in the mapping file.

We have a unit test with an specific HashMap. That's exactly the same for
collection like ArrayList, ...
* See the class HashMapElement which implement the interface
ManageableCollection
* See the unit test HashMapTest.
* Check in the mapping file "jcrmapping.xml" the mapping descriptor for the
class o.a.j.ocm.testmodel.hashmap.Main which contains a descriptor based on
the HashMapElement class.

Hi,

Thanks for the reply.

I will refer to the jackrabbit project in future. I did not realize that the process has happened.
I looked at the example for HashMap. And I have implemented the case of ArrayList, Set etc.
In this scenario this ElementsList extends ArrayList. And I was not sure how I can specify that mapping.

Thanks again,
Raji

If you have time, I will add add a new unit test with an ArrayList (hope for
this wk).

Christophe
