  org.castor.persist.proxy.LazyHashSet<E>

All Implemented Interfaces:

java.lang.Iterable<E>, java.util.Collection<E>, java.util.Set<E>, LazyCollection<E>, TxSynchronizable

public final class LazyHashSet<E>
extends java.lang.Object
implements LazyCollection<E>, java.util.Set<E>

It is a lazy Collection. The collection initially contains only the identities of elements of one type. If any element is needed, it will be fetched "on the fly".
