Package	Description

Class	Description
AbstractEntityEntry	A base implementation of EntityEntry.
AbstractEntityEntry.BooleanState	Represents a boolean flag stored within a number value, using one bit at a specified offset.
AbstractEntityEntry.EnumState<E extends Enum<E>>	Represents an enum value stored within a number value, using four bits starting at a specified offset.
BatchFetchQueueHelper
CacheHelper
Cascade	Delegate responsible for, in conjunction with the various actions, implementing cascade processing.
CascadePoint	Describes the point at which a cascade is occurring
Collections	Implements book-keeping for the collection persistence by reachability algorithm
EntityEntryContext	Defines a context for maintaining the relation between an entity associated with the Session ultimately owning this EntityEntryContext instance and that entity's corresponding EntityEntry.
EntityEntryContext.EntityEntryCrossRef	Used in building the EntityEntryContext.reentrantSafeEntityEntries() entries
EntityEntryExtraStateHolder	Contains optional state from EntityEntry.
ForeignKeys	Algorithms related to foreign key constraint transparency
ForeignKeys.Nullifier	Delegate for handling nullifying ("null"ing-out) non-cascaded associations
ImmutableEntityEntry	An EntityEntry implementation for immutable entities.
ImmutableEntityEntryFactory	Factory for the safe approach implementation of EntityEntry.
ManagedTypeHelper	This is a helper to encapsulate an optimal strategy to execute type checks for interfaces which attempts to avoid the performance issues tracked as JDK-8180450; the problem is complex and explained better on the OpenJDK tracker; we'll focus on a possible solution here.
ManagedTypeHelper.ManagedEntityConsumer
ManagedTypeHelper.PersistentAttributeInterceptableAction<T>	This interface has been introduced to mitigate JDK-8180450. Sadly, using BiConsumer will trigger a type pollution issue because of generics type-erasure: BiConsumer's actual parameters types on the lambda implemention's BiConsumer.accept(T, U) are stealthy enforced via checkcast, messing up with type check cached data.
ManagedTypeHelper.SelfDirtinessTrackerAction<T>
ManagedTypeHelper.SelfDirtinessTrackerConsumer
MutableEntityEntry	An EntityEntry implementation for mutable entities.
MutableEntityEntryFactory	Factory for the safe approach implementation of EntityEntry.
NaturalIdResolutionsImpl
NonNullableTransientDependencies	Tracks non-nullable transient entities that would cause a particular entity insert to fail.
Nullability	Implements the algorithm for validating property values for illegal null values
Nullability.NullabilityCheckType
SessionEventListenerManagerImpl
StatefulPersistenceContext	A stateful implementation of the PersistenceContext contract, meaning that we maintain this state throughout the life of the persistence context.
StatisticalLoggingSessionEventListener	Tracks and logs certain session-level metrics.
TwoPhaseLoad	Functionality relating to the Hibernate two-phase loading process, that may be reused by persisters that do not use the Loader framework
UnsavedValueFactory	Helper for dealing with unsaved value handling
Versioning	Utilities for dealing with optimistic locking values.
