>
> We need to make sure that {{HaltedTraverserStrategy}} recurses into
> collections. This will be elegantly handled by updated {{DetachedFactory}}
> and {{ReferenceFactory}} accordingly.
> For instance:
> {code}
> public static <D> D detach(final Object object) {
> if (object instanceof Element) {
> return (D) ReferenceFactory.detach((Element) object);
> } else if (object instanceof Property) {
> return (D) ReferenceFactory.detach((Property) object);
> } else if (object instanceof Path) {
> return (D) ReferenceFactory.detach((Path) object);
> } else if (object instanceof List) {
> final List list = new ArrayList();
> for (final Object item : (List) object) {
> list.add(ReferenceFactory.detach(item));
> }
> return (D) list;
> } else if (object instanceof Set) {
> final Set set = object instanceof LinkedHashSet ? new
> LinkedHashSet() : new HashSet();
> for (final Object item : (Set) object) {
> set.add(ReferenceFactory.detach(item));
> }
> return (D) set;
> } else if (object instanceof Map) {
> final Map map = object instanceof LinkedHashMap ? new
> LinkedHashMap() : new HashMap();
> for (final Map.Entry<Object, Object> entry : ((Map<Object,
> Object>) object).entrySet()) {
> map.put(ReferenceFactory.detach(entry.getKey()),
> ReferenceFactory.detach(entry.getValue()));
> }
> return (D) map;
> } else {
> return (D) object;
> }
> }
> {code}
