Package org.hibernate.engine

This package contains classes that are "shared" by other packages, and implementations of some key algorithms.

          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 Implements cascaded save / delete / update / lock / evict / replicate / persist / merge
CascadeStyle A style of cascade that can be specified by the mapping for an association.
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.
CollectionLoadContext Represents the state of collections currently being loaded.
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.
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  
Versioning Utility methods for managing versions and timestamps
VersionValue A strategy for determining if a version value is an version of a new transient instance or a previously persistent transient instance.
