Description

Interface Summary

HibernateIterator	An iterator that may be "closed"
JoinSequence.Selector
Mapping	Defines operations common to "compiled" mappings (ie.
ParameterBinder.NamedParameterSource
PersistenceContext	Holds the state of the persistence context, including the first-level cache, entries, snapshots, proxies, etc.
SessionFactoryImplementor	Defines the internal contract between the SessionFactory and other parts of Hibernate such as implementors of Type.
SessionImplementor	Defines the internal contract between the Session and other parts of Hibernate such as implementors of Type or EntityPersister.

Class Summary

ActionQueue	Responsible for maintaining the queue of actions related to events.
BatchFetchQueue	Tracks entity and collection keys that are available for batch fetching, and the queries which were used to load entities, which can be re-used as a subquery for loading owned collections.
Cascade	Delegate responsible for, in conjunction with the various actions, implementing cascade processing.
CascadeStyle	A contract for defining the aspects of cascading various persistence actions.
CascadeStyle.MultipleCascadeStyle
CascadingAction	A session action that may be cascaded from parent entity to its children
CollectionEntry	We need an entry to tell us all about the current state of a collection with respect to its persistent state
CollectionKey	Uniquely identifies a collection instance in a particular session.
Collections	Implements book-keeping for the collection persistence by reachability algorithm
EntityEntry	We need an entry to tell us all about the current state of an object with respect to its persistent state
EntityKey	Uniquely identifies of an entity instance in a particular session by identifier.
EntityUniqueKey	Used to uniquely key an entity instance in relation to a particular session by some unique property reference, as opposed to identifier.
ExecuteUpdateResultCheckStyle	For persistence operations (INSERT, UPDATE, DELETE) what style of determining results (success/failure) is to be used.
FilterDefinition	A FilterDefinition defines the global attributes of a dynamic filter.
ForeignKeys	Algorithms related to foreign key constraint transparency
ForeignKeys.Nullifier
IdentifierValue	A strategy for determining if an identifier value is an identifier of a new transient instance or a previously persistent transient instance.
JoinHelper
JoinSequence
NamedQueryDefinition	Definition of a named query, defined in the mapping metadata.
NamedSQLQueryDefinition	Definition of a named native SQL query, defined in the mapping metadata.
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.
QueryParameters
ResultSetMappingDefinition	Keep a description of the resultset mapping
RowSelection	Represents a selection of rows in a JDBC ResultSet
StatefulPersistenceContext	A PersistenceContext represents the state of persistent "stuff" which Hibernate is tracking.
Status	Represents the status of an entity with respect to this session.
SubselectFetch
TransactionHelper	Allows work to be done outside the current transaction, by suspending it, and performing work in a new transaction
TwoPhaseLoad	Functionality relating to Hibernate's two-phase loading process, that may be reused by persisters that do not use the Loader framework
TypedValue	An ordered pair of a value and its Hibernate type.
UnsavedValueFactory
ValueInclusion	An enum of the different ways a value might be "included".
Versioning	Utilities for dealing with optimisitic locking values.
VersionValue	A strategy for determining if a version value is an version of a new transient instance or a previously persistent transient instance.
