## org.apache.cayenne.access
Class ToManyList

    java.lang.Object
      org.apache.cayenne.access.ToManyList

All Implemented Interfaces:
  java.io.Serializable, java.lang.Iterable, java.util.Collection, java.util.List, ValueHolder

    public class ToManyList

extends java.lang.Object
implements java.util.List, java.io.Serializable, ValueHolder

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.

For more information see Cayenne User Guide.
