Re: [Simple-support] How do you access field annotations from a custom Converter?

the outputnode contains the name, see getName()

For some of my more complex data structures, I need to write my own Converters. For instance, say I have a List<List<String>> that I need to marshall. I've written the following:


    class WorldObject {


       @Element(name="vector-names")
       @Convert(ListListConverter.class)
       private List<List<String>> vectorNames;

       /** Constructor and other details elided... **/



    }

Along with the ListListConverter (I've left out the unmarshaller for the moment):

    class ListListConverter implements Converter<List<List<String>>> {
 
       @Override


       public List<List<String>> read(InputNode node) throws Exception {
          // stub
          return null;
       }   

       @Override
       public void write(OutputNode node, List<List<String>> value)


             throws Exception {
          
          node.setName("list-list-string");
          
          for (List<String> list : value) {
             OutputNode subList = node.getChild("list-string");


             
             for (String str : list) {
                OutputNode stringNode = subList.getChild("string");
                stringNode.setValue(str);
             }
                   


             subList.commit();
          }
          
          node.commit();
          
       }
       
    }

This setup works fine, and produces the XML I want. I would, however, like to have access to the `@Element` annotation's `name` field so that I can give the tags the specified name (in this case, `"vector-names"`) rather than the default name (`"list-list-string"`). This is how marshalling works for all the types that Simple handles out of the box, so there must be a way to access that data from a custom Converter.



How can I accomplish this?

Thank you very much,
