public abstract class AbstractLRSProxyCollection extends Object implements Set, LRSProxy, Predicate, CollectionChangeTracker
iterator()
may perform a database
query. Changes to the collection are tracked through a
ChangeTracker
. This collection has the following limitations:
size
method may return Integer.MAX_VALUE
