public class PersistenceOptimizingArrayList
extends java.util.ArrayList

An array list which automatically remembers it add and remove history. This history makes StorePersister able to skip unnecessary db updates, which speeds things up.

To make your db updates more affective, just use this class for your collections and make sure that you return iterators through one of the iterator methods on this class, i.e. Collections.unmodifiableCollection(myLisat).iterator will not make things any fatser.
