# Class ToManyList<E>

java.lang.Object
org.apache.cayenne.util.RelationshipFault<E>
org.apache.cayenne.util.PersistentObjectList<E>
org.apache.cayenne.access.ToManyList<E>

All Implemented Interfaces:
  `Serializable, Iterable<E>, Collection<E>, List<E>, SequencedCollection<E>, PersistentObjectCollection<E>, ValueHolder<List<E>>`

public class ToManyList<E> extends PersistentObjectList<E> implements Serializable
A list that holds objects for to-many relationships. All operations, except for resolving the list from DB, are not synchronized. The safest way to implement custom synchronization is to synchronize on parent ObjectStore.
