## Package org.hibernate.engine.internal

Interface Summary
JoinSequence.Selector
ParameterBinder.NamedParameterSource

Class Summary
Cascade: Delegate responsible for, in conjunction with the various `actions`, implementing cascade processing.
Collections: Implements book-keeping for the collection persistence by reachability algorithm
ForeignKeys: Algorithms related to foreign key constraint transparency
ForeignKeys.Nullifier
JoinHelper
JoinSequence
NaturalIdXrefDelegate: Maintains a `PersistenceContext`-level 2-way cross-reference (xref) between the identifiers and natural ids of entities associated with the PersistenceContext.
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
ParameterBinder: Centralizes the commonality regarding binding of parameter values into PreparedStatements as this logic is used in many places.
StatefulPersistenceContext: A stateful implementation of the `PersistenceContext` contract meaning that we maintain this state throughout the life of the persistence context.
TwoPhaseLoad: Functionality relating to Hibernate's two-phase loading process, that may be reused by persisters that do not use the Loader framework
UnsavedValueFactory
Versioning: Utilities for dealing with optimistic locking values.
