Re: [Simple-support] ElementMap question

[Niall G. <gal...@ya...>]

Hi,

Have a look at the Dictionary class in org.simpleframework.xml.util. This looks like what you want. In order to use attributes in the value it has to be a sub-element of the entry and can not go in the entry element. For example:

<entry key="key>
   <value a="a" b="b" c="c"/>
</entry> 

In order to get a flat list you will need to use an ElementList. The Dictionary (which is a HashSet) object can make use of an attribute to do this. It has a get() method. If you want you can use an ElementList and transfer this via some key to a map using the @Commit annotation like so.


public class MyClass {
  
  @ElementList(inline=true)
  private List<Foo> list;
  private Map<Integer, Foo> map;

  @Commit
  private void commit() {
     for(Foo foo : list) {
        map.put(foo.level, foo);
     } 
  }
}

Hope this helps.

Niall
