/**
 * Update an existing article by copying properties from the new one over.  Note that we can't call saveOrUpdate,
 * since the new article is not a persistent instance, but has all the properties that we want.
 * <p/>//from  w ww .  ja v a  2 s .  co m
 * See <a href="http://stackoverflow.com/questions/4779239/update-persistent-object-with-transient-object-using-hibernate">this
 * post on stack overflow</a> for more information
 * <p/>
 * For collections, we clear the old property and add all the new entries, relying on 'delete-orphan' to delete the
 * old objects. The downside of this approach is that it results in a delete statement for each entry in the old
 * collection, and an insert statement for each entry in the new collection.  There a couple of things we could do to
 * optimize this: <ol> <li>Write a sql statement to delete the old entries in one go</li> <li>copy over collection
 * properties recursively instead of clearing the old collection.  e.g. for {@link Article#assets}, instead of
 * clearing out the old list, we would find the matching asset by DOI and Extension, and update its properties</li>
 * </ol>
 * <p/>
 * Option number 2 is messy and a lot of code (I've done it before)
