메소드 설명
AddChildParent ( object child, object parent ) : void
AddCollectionHolder ( IPersistentCollection holder ) : void

Register a PersistentCollection object for an array. Associates a holder with an array - MUST be called after loading array, since the array instance is not created until endLoad().

AddEntity ( object entity, Status status, object loadedState, NHibernate.Engine.EntityKey entityKey, object version, LockMode lockMode, bool existsInDatabase, IEntityPersister persister, bool disableVersionIncrement, bool lazyPropertiesAreUnfetched ) : EntityEntry

Adds an entity to the internal caches.

AddEntity ( NHibernate.Engine.EntityKey key, object entity ) : void

Add a canonical mapping from entity key to entity instance

AddEntity ( NHibernate.Engine.EntityUniqueKey euk, object entity ) : void

Add an entity to the cache by unique key

Generates an appropriate EntityEntry instance and adds it to the event source's internal caches.

AddInitializedCollection ( ICollectionPersister persister, IPersistentCollection collection, object id ) : CollectionEntry

add a collection we just pulled out of the cache (does not need initializing)

AddInitializedDetachedCollection ( ICollectionPersister collectionPersister, IPersistentCollection collection ) : void

add an (initialized) collection that was created by another session and passed into update() (ie. one with a snapshot and existing state on the database)

AddNewCollection ( ICollectionPersister persister, IPersistentCollection collection ) : void

GetCollectionEntry ( IPersistentCollection coll ) : CollectionEntry

Get the collection entry for a persistent collection
