[Mdarad-toolbox-devs] Comparator modifications

[<fra...@po...>]

Hi,

I made some important modifications to the way the entity class is 
generated.  The entity classes do not implement the Comparable interface 
anymore.  Instead, I have generated an EntityComparator on the side.  
Now for associations inside an entity, they are now stored in a:

new TreeSet(<comparatorClass>) rather than in a simple TreeSet.

I had some regression problems implementing this but I think I fixed 
them all.  Just in case though, if you get a ClassCastException in the 
Hibernate StoredSet class, keep in mind that it is probably because you 
are trying to save a list, set or collection that is not a SortedSet.  
This means that you should not do:

Collection collection = new HashSet();
product.setItems(collection);

but rather:

Collection collection = new TreeSet(ItemComparator);
product.setItems(collection);

You should almost never have to set the collection though. The proper 
way to do this would be to iterate in the collection and to add them 
individually or:

Collection collection;
...
product.getItems().clear();
product.getItems().addAll(collection);

If you have any questions let me know.
