Public Constructors
	OneToManyPersister(Collection collection, CollectionRegionAccessStrategy cacheAccessStrategy, Configuration cfg, SessionFactoryImplementor factory)

Public Methods
boolean	consumesCollectionAlias()
boolean	consumesEntityAlias()
String	filterFragment(String alias)
String	fromJoinFragment(String alias, boolean innerJoin, boolean includeSubclasses)
Object	getElementByIndex(Serializable key, Object index, SessionImplementor session, Object owner)
String	getTableName() The table to join to.
boolean	isCascadeDeleteEnabled()
boolean	isManyToMany() Is this a many-to-many association? Note that this is mainly a convenience feature as the single persister does not conatin all the information needed to handle a many-to-many itself, as internally it is looked at as two many-to-ones.
boolean	isOneToMany()

String	whereJoinFragment(String alias, boolean innerJoin, boolean includeSubclasses)

Protected Methods
CollectionInitializer	createCollectionInitializer(LoadQueryInfluencers loadQueryInfluencers) Create the `OneToManyLoader`
CollectionInitializer	createSubselectInitializer(SubselectFetch subselect, SessionImplementor session)
int	doUpdateRows(Serializable id, PersistentCollection collection, SessionImplementor session)
String	generateDeleteRowString() Generate the SQL UPDATE that updates a particular row's foreign key to null
String	generateDeleteString() Generate the SQL UPDATE that updates all the foreign keys to null
String	generateInsertRowString() Generate the SQL UPDATE that updates a foreign key to a value
String	generateUpdateRowString() Not needed for one-to-many association
